Issues with code persistence, regressions, and disabled preview buttons

Hello community,

I am currently building my first application using Google AI Studio, but I am facing significant stability issues. I would appreciate some guidance on the following points:

1. Model “Amnesia” and Regressions After a few turns in the conversation, the model seems to ignore new instructions. It explicitly claims to have applied fixes (“I have made the requested changes…”), but when I check the code, nothing has changed. Worse, parts of the code that were previously working fine suddenly break or disappear. I am unable to stabilize the app due to this behavior.

2. UI Issues: Disabled Buttons I noticed that several UI controls are grayed out and unusable:

  • The device preview selector.

  • The app reload button.

  • The full-screen button. Is this a known bug?

3. Pricing and Quotas Could you clarify the usage limits for the “Build” section?

  • Is it free forever?

  • Are there specific daily or monthly limits on chats or tokens?

Thank you for your help!
