T-Mobile / AT&T / Verizon missing messages (RCS) - I am seeing message in Android Stock / System messaging app but not in Textra SMS
That's the issue, although really it's a half baked Android implementation if you can receive messages in an inactive app (stock) and not get any notifications, right!? It's also your MOBILE CARRIER trying to lock you in to their messaging app, not good.
AT&T: You can disable RCS messages to you in your Android Stock / System messaging app under Settings > Advanced Messaging > Use Advanced Messaging = OFF (make the Android Stock / System messaging app the DEFAULT app first in order to be able to change the setting).
T-Mobile Solution 1: On some phones, you can disable RCS messages to you in your Android Stock / System messaging app under Settings > Enhanced messaging = OFF (make the Android Stock / System messaging app the DEFAULT app first in order to be able to change the setting).
If this setting is not appearing, do the following:
- From any Home screen, tap Phone.
- Tap the MORE icon.
- Tap Settings.
- Tap Voice over LTE settings.
- Select "Do not use VoLTE"
T-Mobile Solution 3: Some users report switching to the Android Stock / System messaging app, making it the DEFAULT and then switching back to Textra SMS and making it the DEFAULT works.
T-Mobile Solution 4 (digits): Android Settings > Cloud and Accounts > Multi-line settings (tap the 3 dots in the top right corner for more options) and select "log out"
Verizon: Messages app, tap the settings button (three vertical dots) on the top right of the Messages app. Tap Settings. Tap Chat features. If the Enable chat features toggle is turned on, turn it off by tapping it once.
Confirm if that fixes it please and report back so we can help others.
