🛠️ Business Is Already Sharing This WhatsApp Account With a Partner 🔐

You may see an error saying:

*"Your phone number isn't eligible to connect to the WhatsApp Business Platform. More activity on the WhatsApp Business App is needed to help determine eligibility."

Why it happens?

Meta requires that the number has been active on the WhatsApp Business App for at least 7 days. If the number is new or hasn’t seen enough activity, it won’t qualify yet.

How to fix it:

• Use the number actively: Engage in real conversations with customers through the WhatsApp Business App for at least 7 days (ideally 30–60 days). 💬

• Avoid re-registering: Don’t delete and re-register the number—it resets activity history. ❌

• Check for old WABA account: If this number was previously linked to a WhatsApp Business API (WABA) account, delete the old setup first, then re-register and use it actively for 1–2 months before trying Coexistence again. 🔄

🛠️ Country or region not supported 🌍

Why it happens?

Meta has temporarily restricted Coexistence in certain countries due to compliance or service limitations (e.g., Nigeria, South Africa).

How to fix it:

• Use a supported country code: Choose a number from supported regions like India, Brazil, Mexico, Indonesia, the U.S., Hong Kong, or Singapore. ✅

• Monitor for updates: Meta may expand support over time.

• Explore alternatives: If your region isn’t supported yet, use the WhatsApp Business App alone or another communication channel temporarily.

🛠️ Chat sync failures or delays ⏳

Why it happens?

Chat history and contact data might take a long time to sync (up to 6 hours), or fail altogether.

• Large chat history 📂

• Unstable internet connection 🌐

• WhatsApp Business App closed or inactive during sync ❌

How to fix it:

• Keep the app open 📱

• Use a reliable internet connection ⚡

• Be patient ⏱️

• Restart the process if needed: Rescan the QR code and retry. Make sure your app is updated to version 2.24.17 or later. 🔄

🛠️ QR code doesn’t appear or won’t scan 📷

Why it happens?

The QR code for embedded signup either doesn’t appear or fails to scan.

• Outdated app version

• Incorrect signup steps

• Device camera issues

• Temporary server issues

How to fix it:

• Update your app ⬆️ : Ensure the WhatsApp Business App is updated to version 2.24.17 or newer.

• Follow the correct flow: Settings > WhatsApp > Sign Up with Facebook in the app to generate the QR code.

• **Use a working camera: **Make sure your phone camera is clean and functioning properly. Try scanning in good lighting conditions

• **Retry : **If issues persist, try again after some time.

🛠️ Facebook Page linking issues 🔗

Why it happens?

You may not be able to link your WhatsApp Business account to a Facebook Page, required during Coexistence setup.

• No Facebook Page or Meta Business Manager account

• Not logged in as admin

• Regional/account-level restrictions

How to fix it:

1. Create a Facebook Page 🏢 : If you don’t already have one, go to Settings > Business Tools > Facebook & Instagram in the WhatsApp Business App and create it from there.

2. Verify admin access ✔️ : Make sure you're logged in with an account that has admin privileges for both the Facebook Page and the Business Manager

3. **Check Meta Business Account setup : **During Embedded Signup, connect to or create a Meta Business Account. Make sure the account has complete business info like name, address, and website.

🛠️ Inability to disable Coexistence ❌

Why it happens?

No built-in option exists in the WhatsApp API platform to turn off Coexistence directly.

• The feature isn’t available in the API interface.

How to fix it:

• Disconnect from the app: Settings > Account > Business Platform > Disconnect

• Don’t uninstall the app 🚫

🛠️ Unsupported companion devices 📵

Why it happens?

Messages from some devices (like WhatsApp for Windows or WearOS) don’t sync with the Cloud API.

• Only selected companion apps (WhatsApp Web, WhatsApp for Mac) are supported.

How to fix it:

• Use supported devices 💻 : After onboarding, re-link your devices using WhatsApp Web or WhatsApp for Mac.

• Watch for placeholders ⚠️ : If messages are sent from unsupported devices, placeholders may appear prompting users to switch.

• Check for updates 🔔 : Meta may expand support for more devices soon. Follow updates from Meta or ChatDaddy.

🛠️ Business name can’t be changed post-onboarding 🏷️

Why it happens?

You can’t change your business name after enabling Coexistence.

• Meta locks the business name for consistency across both platforms.

How to fix it:

• Update before onboarding ✍️

• Need changes after onboarding? Contact Meta support or ChatDaddy—updates may not always be approved.

🛠️ Invalid Access Code Issue

Why it happens?

You may encounter an “Invalid Access Code” error even when you are entering the correct passcode.

• This typically happens due to a temporary verification or syncing delay on Meta’s side.

How to fix it:

• Please wait and retry after 1–3 working days.

In most cases, the system refreshes automatically and the issue is resolved without needing further action.

Quick checklist for a smooth setup ✅

• Update your app to the latest **version **

• Use official providers like ChatDaddy for guidance 🛡️

• Check number eligibility: 7+ days active and supported country

• Back up important data 💾
