We currently have a temporary fix for Showmax which you can access here: CloudGate
It is always good to try downgrade your actual app and see if that works. We are working with both apps to find a solution that gets them to work with no hassles.
Try avoid updating the apps. As the CloudGate Circle is running Android 4.4, sometimes updated apps do not work on the device. You will still be able to access content and use the app if you do not update it.
We will always advise you on when you should update the device.
Please note we can not take responsibility for 3rd part applications on the device.
