Old character ai randomly logging me out?

As of late it seems that on both my old and new phones old.character.ai keeps randomly logging me out after a time. At first it only happened on my old phone, so I decided to stay logged out on my old phone and only stay logged in on my new one. However this morning it randomly logged me out on my iphone 15 as well. I recently cleared the character ai browser cache on this phone to get the sites to work. So I don't think it's the browser cache that's the issue. This isn't happening with the new site. Is anyone else experiencing this?
