Can't get help with lightroom android refusing to export photos. Ideas?

For over a month now lightroom has refused to export photos (it works once in a blue moon, seemingly at random). I try to export one photo at a time and it will stay on the "exporting screen" for 30+ minutes if I let it. I can export pictures with no edits or pictures with edits If i export as the "small" size but that about it. Things are synched fine.

I've spoken with 5 support agents now via chat and every. single. one. has just left in the middle of the chat. Not disconnected, just left. I have screenshots of this and I cannot get anyone to actually see the issue through. 

I'm out of ideas, what do you think I should do if I'd like to continue using lightroom? Beyond frustrating. TYIA for any ideas you can provide!
