Clearing GaiaGPS App cache (temporary files, tile cache)

I am having same issue as unresolved post/s others described (a year ago), and one submitted a month ago. None resolved.

Clear Cache in the iOS App doesn't appear to do anything. I have 17.56 GB of Temporary Files and 1.87 GB of Tile Cache. Nothing I've found or tried clears these caches to free up space.

PS: the Topics dropdown here in Help does not have bug report as a selection. Had to use Feature Requests.
