Doesnt work on iphone7

It doesnt work when you login. App just spins and then a DIRECTV logo on a black screen. Called tech support and was told that the app doesnt work for the iphone7. The phone has been out a while now, I dont understand how they arent up to date yet. Especially with the last push on June 26

BAustinRob about DIRECTV, v5.0.105
