Recently you updated your app.... as a result many buttons are now one on top of the other.for example (the sync button is on the menu button).
The garmin app uses the language setting of the mobile phone rather than it's own defined language so there is no way to use the app other than changing the phone language.
many screens are effected:
1. cant see fiend list
2.can't see group history activities
3.can't see my own activities
etc...
Something with your screen alignment is very wrong and it's affect languages which are right to left rather than left to right.
Most of us can handle English if you only allow to set app language from the app itself - this is a good fix until the issue is resolved.
