I cannot import files from the PC by scanning the QR code.
I get a message stating that the XML code is newer than the Android app. What should I do?
Make sure you are using a matching mobile app version as the XML and QR Export are not compatible if you have eg V11 Beta desktop and try to use the V10 mobile app.
V11 Beta on Android is due out shortly on the Playstore. If it’s not there already then it shouldn’t be far away as per @Michal_Burger advised below.
