Don't expect much help from the support on here, they don't seem to know much. The Showmax app is not properly supported on this unit, its very frustrating when you can't watch the movie you want for a service that you have paid for on a machine that is not properly supported.
The workaround, Load Showmax into KODI, it works as intended from the KODI base.
Mygica Support, you need to up your game, this is not the 1st time that people have asked about this and I was about to bin this unit and buy something more reliable before I stumbled upon this. I have said this before and I'll say it again, this is my 2nd and my last machine that I will own from Mygica.
