Maximum limit in conversation?

I’m using ChatGPT on both my android and the web version on my PC and it has been syncing alright until recently, and now newer parts of the conversation history that I had on my PC aren’t showing up on the mobile app at all. I’m worried that if I keep chatting on mobile it will overwrite the conversation I had on my PC.
Has anyone else experienced this? Is there an easy fix? Do I just need to keep waiting?

Edit: After several tries, it’s not just a sync issue, the chat is simply stuck in the middle of one message. If I try to continue from there or start over earlier in the conversation, it will overwrite all of the new messages and reset to the one bugged out message.
I’m not sure if this is an issue with the conversation being too long or what, but it seems like a lost cause.

I tried messaging from the old point on mobile and it responded and then deleted the new message, going back to the old point.
This has happened twice.

I edited an earlier message on mobile to try and start the conversation over before the problem started and it worked for a while then deleted all of the new conversation, readding my message that I had replaced and it’s own, half-generated response.
