Issues with Access to GPT-о1 and Plus Subscription Features

Help! I’ve encountered the following issues:

  1. Instead of GPT-о1 and GPT-3 mini, I’m getting responses from a different GPT-4 model. I purchased a Plus subscription but can’t use the advanced models at all.

  2. Web search isn’t working.

  3. In created projects, GPT can’t read project files—it doesn’t see them at all.

  4. Since when does GPT-4o have a limit? Why do I have restrictions on this model with a Plus subscription? I don’t understand! I’m paying money, not to have features taken away from me!
