Hi and thank you for answering. Yes I do use MapView. If it may be usefull this is what Google Play console reports:

I will try you suggestion. I know I already asked but I still don’t understand UXL. Do you mean that I have to create a .UXL file with <Extensions>... inside and save it in the root folder of the app?
Thank you for the patience.
