Thank you for your answer.
I believe there is a misunderstanding.
This TomTom Navigatore GPS - Traffico e Autovelox v1.18.01 app has already been installed with the Western Europe map on the SD-card of my S20 Ultra for over a year and I have made some updates to the map without problem. Since upgrading to Android 11, I can no longer update the map (SD-card). In addition, I cannot remove my SD-card because several apps are installed on it and my S20 will not work properly.
Regards
