Lost SD card writing authorization
Worked fine until recently.
But now, no more write access to SD card, either for GPX saving, nor for offline maps download. I didn't change anything before this issue happened.
Checked storage authorization for this app in Android settings : ok.
Searched in GPX viewer Pro settings : didn't find any solution.
Tried to restart phone, to clean cache, and even to uninstall and reinstall: useless.
Other apps don't have any problem.
