Android 7 has some issues and an update is supposed to be released. I am on the beta version so I don't know if the general release has happened yet or not.
Analysis frozen on app

I had a chess.com app working on my BlackBerry.
However, when some "genious" decided to upgrade the app (for reasons beyond my imagination, why [no need for expletives -- MOD] do people insist on breaking working stuff with they stupid 'upgrades'?), it stopped working.
Yet another great example of [removed -- MOD] customer treatment I've experienced on this site, I'm glad I downgraded my membership today and I'll recommend everyone else to follow my example.
This place used to be OK, but now it's run by morons and [removed -- MOD]

How do you get the beta version?
It's been a while but I think I got it from joining a G+ group. I'll try and find more information later.

{removed -- Nullis } you, MOD.
Stop acting like a child and fix your {removed -- Nullis } {removed -- Nullis } {removed -- Nullis } stupid decision makers.
Whoever came up with the bright idea of spamming PAYING, LONG TIME customers should be {removed -- Nullis } fired on the spot!
Sincerely and {removed -- Nullis } you once again,
Nullis

Hey guys,
I love the chess.com app! It's a ton of fun. I really like watching my games with the analysis, but recently it has been freezing. On my phone, whenever I go to do an analysis, it loads about three or four moves, and then it just gets stuck. If I try to do it over it says there is a game already being analyzed.
My phone just updated it's OS to Android 7.0 Nougat, and maybe that has something to do with it. This is a real bummer for me. Hope someone knows something.
