These improvements are really important for App Inventor:
Target SDK 36 — App Inventor is still using Target SDK 35. It should be updated to SDK 36 to stay compatible with the latest Android/Google Play requirements.
Package Name Change — Please provide an easy way to change the default package/application ID when building an app, without having to manually modify generated files.
Same goes for you. Just be patient.
The AI2 Test Builder (https://ai2-test.appinventor.mit.edu/) is already using Target SDK 36, which is great, but it does not provide an option to change the Package Name / Application ID.
In the Offline Builder, the Package Name can be changed, but it is still limited to Target SDK 35.
Could you please provide a stable release with Target SDK 36 + Package Name/Application ID customization?
Having both features in one stable version would be extremely helpful for developers who want to publish and maintain apps on Google Play. 
I guess you mean AI2Offline. That is not developed by the App Inventor team. Since App Inventor is an educational tool I always think it is no problem using a package name with App Inventor in it.
Got it, I understand. Thank you for clarifying!
