We are experiencing an issue with a ManyChat Messenger QR Code / Ref URL trigger on Android.
On iOS, everything works correctly: the user scans the QR code, Messenger opens, and the correct automation starts.
On Android, the QR code is read correctly and Messenger opens the Facebook Page conversation, but the automation does not start.
The strange part is that the exact same m.me URL works if we:
1. Copy the URL generated by the QR code.
2. Paste it manually into Chrome.
3. Open it from Chrome.
In that case, Messenger opens and the ManyChat automation starts correctly.
We have already tested:
- The QR code with and without a logo.
- Different QR reader applications.
- Opening the QR directly with the Android camera.
- Refreshing Facebook permissions in ManyChat.
- Confirming that the automation and trigger are published.
- Using an intermediate web page with a button that links to the same m.me URL.
The intermediate button also opens Messenger, but the automation still does not start. Only manually pasting the URL into Chrome works.
It appears that when Android opens the m.me link directly in Messenger, the ref parameter may not be processed or passed correctly.
Has anyone experienced this behavior on Android? Is there a known configuration, workaround, or reliable alternative for Messenger QR Code / Ref URL triggers?
