Not sure if there's a minimum OS requirement with the app. My M8S is running 4.4. I put the app on another box of mine running 7.1.1 and it works there.
Does anyone have the app running on 4.4 by chance? 

Also, is anyone else seeing the older version updating itself to the new one after a short period of time?   

Can you guys see the blue loading animation when you click on play? Maybe juste a milisecond. 

IF SO : Simply retry and after 3 or 4 times it will work.

IF NOT: You guys have the latest version ( 6.2.0.9311 )  and need to rollback to an older version :

Hi bud.  I'm encountering the 'mirroring not supported' on my Nexbox, Android 6, with the latest update.  I tried following your instructions and roll back but when I go to your provided link all there is a version for 6.2.2.9352 not the 6.1.9152 mentioned in your post.  BTW, just grabbed a new tablet, also Android 6, and the latest version via playstore is working fine.  Well, except for the usual Bell problems, like no access to a whack of channels to which I"m subscribed, but it is Bell we're talking about, eh?   

 You have to scroll down to older versions.... But I'm also seeing the "Mirroring Not Supported" on older versions too. It may work after trying the first time or two, but then it goes back to that message and can't get rid of it for any channel, no matter how many times I try.  

 Version 6.1.9152 installed and getting the same message.  Tried it five times.  Man, I wish they'd fix this rubbish.  Grrrrr . . . 

The one time I called when having troubles with this, the CSR didn't even know this app worked for those of us on Sat TV.  Bell:  useful at sending out bills and not much else.
