since software update iOS 11 I neither have access to my tresor in the Cryptomator folder on the iCloud drive nor can I create a new one. The error message is: “iCloud Drive-Authentication fehlgeschlagen.” But working with iCloud via the new Dateien app works well. When I delete the Cryptomator folder, a new one is created by the Cryptomator app. But still no access to it. I’m running Cryptomator V1.2.6 (488) , iOS 11.0.2 on an iPad Air 2. Any suggestions?
