There are a few things that can cause you to see a "Transaction Failed" error when purchasing UDisc Pro on an Android device:


First, make sure UDisc has access to use data on your device. If you've done that and still have this issue try the following:


Go to Installed Apps -> Google Play Store -> Permission manager, enable "Start in background" permissions.


If you're still unable to purchase and get the error message from the screenshot above, please email team@udisc.com and we'll get you up and running.
