Issues with "Search the web" and "Attach files"

So, I’ve been noticing these lately about 4o. Sometimes, when I try “Search the web” or “Attach files”, the model neither searches the web for information nor tries to read the attached file and just generates content normally. I initially though that it was because I was using ChatGPT in Firefox because I initially did not encounter the issue on Edge and Brave, but recently, I have also been experiencing these issues on those two browser. Additionally, when I try to have it read a file while also attaching a picture, it says that it cannot read the file because of some limitations in the file. I think I may have also encountered this issue even without any picture attached. May I please know if anyone else is also experiencing similar issues? If yes, may I please know if you have any ideas on how to handle this? Thank you.

P.S. Note that I have yet to experience the “Search the web” issue in the ChatGPT mobile app.
