Chatgpt doesn't read pdfs and doesn't respond to prompt on PC

Has anyone else experienced this issue? Whenever I try to use ChatGPT on my PC to read a PDF, it doesn’t work. It keeps saying it can’t read PDFs and only accepts direct text in the chat. When I give it a prompt, it just responds with something like, “Got it, let me know if there’s anything else you’d like to add or modify,” without actually doing what I asked.

At first, I thought it was a bug with my account, but two friends who use ChatGPT told me they have the same problem. However, they mentioned the mobile app works fine. I tested it, and it does work on mobile, but I prefer using my PC for everything. Is anyone else facing this? Could it be related to a recent update?
