App is not installing after exporting from Builder

[Anke]

Is there a way to revert @Niotron

You must add android:exported="true" also for extensions (if necessary): https://community.appinventor.mit.edu/t/android-12-changes/63848/2?u=anke https://community.niotron.com/t/new-app-api-level-31-in-console/9856/64?u=anke Btw, your screenshot does NOT show this error: That’s why I asked you to post it.
