Memory update?

Hi everyone I’ve noticed in the last 3 maybe 4 days or so that ChatGPT has suddenly “forgotten” a lot of saved details outside of chats, also when I try to get it to resave the information it lasts about 5 mins and forgets again and it’s been incredibly frustrating! Does anyone know if there was like a memory bug with an update or anything? And how to restore the old memories if possible? Thanks in advance for any help and advice!
