Hello there,
I got the Nothing 3(a) Pro last Friday. I love a lot about it, however, I am constantly experiencing issues with the abovementioned apps.
Facebook: I shared a story on FB, then wanted to share it on Instagram - the button on the top right of the FB story (the little Instagram icon) is not working at all, like it is not there at all.
Messenger: Quite often the voice messages from friends can’t be played. Clicking on them does absolutely nothing. Restarting the app often does not help with it - I had to reinstall it a few times.
Instagram: The rewind thingy is not working a lot of the times. Sometimes restarting the app fixes the issue, but in this case it must be done a few times.
NB: all of the apps are up to date when the issues occurred, the system update is up to date, the Facebook and Instagram accounts are linked. I have tried switching to the 3 button layout at the bottom instead of gestures.
NB2: All of these issues are NOT present on my old Xiaomi 11T Pro and work perfectly fine.
