I just updated it and some of the same things as before have continued. such are restarting the roleplay without me pressing the reset, signing me out despite my Internet working for all other AI bot. I don't know if it may be a bug or what not but this was a concern and a bit annoying, some roleplay 'games' on there still doesn't allow my messages to go through. But from the update it had taken 4+ times to reset the app for me to eventually get signed on. I have more but can put it all here.

Seems pretty fun so far! My main problem right now is trying to continue the first story. It wouldn't be so bad If I could post what I've edited so far and then add to it after- That seems like an easy feature but I don't see a way to edit stories after submitting it. I keep trying to edit the story but an error (failed to Regenerate) happens or I leave and the continued story is gone. A simple fix is to make submitted stories editable. UPDATE: they added a draft feature which is a nice comp. :)

Constantly stuck in a load screen and signs me out. Then I gotta sign myself in, and sometimes it just says sign in failed and does the same thing with my story. So won't save them. It won't upload them now. To constantly do this over and over without getting anything done, I have to rewrite everything just so I can get into the app itself. This app used to be a lot of fun to use now. It's just taking up space on my phone. I would not recommend this app for anybody.
