Unable to generate an apk api target level 30

[mrdebug]

Hi, in order to generate an apk with api target level 30 I have to execute qmake, and before to deploy I have to edit the json file
"android-MetronomeTouch-deployment-settings.json"
and change the parameter
"android-target-sdk-version": "28" to "30"
Change qtTargetSdkVersion variable in "gradle.properties" file or edit the file "AndroidManifest.xml" has no effect.
I'm using the lates QtCreator.

Have you had the same experience?

Seems to be solved by deleting Qt and QtProject folders .config
