4o model Chat sessions within a project can't read documents

There seems to be a lot changing within projects, but things are breaking as they make changes.
In the past, when I would have a word document in a project, any 4o model would be able to read the information within that word document. That is no longer the case. I ask the 4o model to tell me about something in the document, and it can’t see it. I give it the name of the document and it says it’s can’t find it. Am I the only one experiencing this? If so, what am I doing wrong? If I’m not, when will they fix it?

Additionally, a lot of the o1 models in a project time out half the time.

It seems what is happening is that if I create a project and then start a 4o model chat session, then it can read any documents that I add to the project, however, if I add an o1 model chat session, it breaks the project and the 4o can no longer see the files. Additionally, the o1 and o1 Pro are much more prone to timing out and not responding.
