This is quite rare but it did happen to me (exactly) once. Report it as a bug, they put very high priority on unable to decrypt reports and my issues stopped happening within a few days (can't promise that is always the result since I don't know what happens behind the scenes, but it won't hurt, and reporting bugs from within the app is pretty straightforward - hit the username icon at top left to get to settings, then "Report a problem").
