Problem with Android target-sdk-version >= 30

Found the issue. The Androidmanifest.xml <application> was missing the attribute
android:allowNativeHeapPointerTagging="false".
It could be a good idea to add it to the android templates, as since November 2022 every update must target SDK >= 31, and apps that don’t do it will be deindexed from search on January 31, 2023.
