Custom GPT not reading knowledge docs

So, i have had no issues since subscribing to Plus, until the last 3 days. CustomGPT will only read 1 page of any document no matter how small i make them. I’ve tried all manner of Doc types, reuploads, renaming etc. ChatGPT can read and pull the info out of the document just fine, but the customGPT seems like it hit itself in the head with a brick. I hope this gets resolved soon.
