In /Tools /Options /Theater View Netflix, Amazon Prime and Amazon Music are explictly listed and available in Theater View by just selecting and choosing "Add".
On my HTPC, after logging in to the service I can easily exit Netflix back to the regular MC display by using "esc" on my keyboard. Same thing if I manually add another streaming service, such as Apple TV+.
But, after logging in to Amazon Prime and Amazon Music, they seem to be one way choices. If I then enter Theater View full screen display to use Amazon Prime or Amazon Music, hitting "Esc" doesn't work. In fact, nothing else is avaliable.
I have to manually close MC (e.g. Task Manager) to get out of Amazon Prime Video or Amazon Music in MC Theater View. None of the CTRL key options work either.
Even worse, if I subsequently re-enter MC Theater View after restarting MC, it seems to put me automatically back full screen into whichever of Amazon Prime Video or Amazon Music was playing in Theater View before I closed MC.
To get Theater View back with its normal menu options I have had to reload my previous library settings (/File/Restore Library/Options/Restore Settings)
Every other streaming service I've added to Theater View lets me get out back to the main Theater View menu by hitting "esc".
I can easily continue to access the services on my HTPC through the Amazon Music app or i the case of Amazon Prime Video with a browser.
It'd just be nice to have it all working in Theater View.
I'm running MC 32.0.6 on Windows 11.
