Hello, @Db69
I appreciate trying everything to resolve the issue, however, if you could list all that was tried that would be helpful to isolate the issue.
When did you first notice the issue? Also, please provide your phone make/model and the OS it's running.
You can also try clearing data/cache then disable the app which should force uninstall the updates. Then you can enable the app and download the updates by visiting Google Play Store.
If the issue is still not resolved I suggest checking with Facebook support.
@Community - anybody else is experiencing a similar issue?
Cheers,
RogersMoin
