For most developers, all that is needed to update your app level is to

  • Bump up your app's version level manually.

  • rebuild your app using the latest version of App Inventor August 25, 2025 nb202b.

  • Use the latest Companion for your build (2.76 or 2.76u).

MIT has added what is needed to update in the latest version of the compiler.

That doesnt work for me. I cant understand why

Why do you think that? Can you elaborate?
Target sdk is 35 and this is all you need nowadays
