Playstore no longer allows the publication of appinventor apps, it shows this warning:
This APK generates code and resources that are not used and sent to users anyway. You can reduce the size of your app using the Android App Bundle format. If you do not optimize the app for user device configurations, it will have a larger download and installation size than what you really need. Larger apps have lower installation success rates and take up more storage space on users' devices.
Use the Android App Bundle format to optimize device configurations automatically or manage them on your own with several APKs.
