Hi,
so right after selecting "Settings > Display and Use > Maintenance > Import calendar from ICS file", the permission request appears? Even before you can select a file and a calendar? I cannot find a permission request there. Are you sure that the new screen is not opened?
Which version do you mean with "latest version"? There are many versions that you could have (Google Play, Google Play Beta, Amazon, Direct version). Please tell me the version number and build number. Thank you very much!
Kind regards
Dominique Gunia
