If I switch out and back in, then everything is fine. 9.15.708 beta
I just have the settings button. When I switch back. I get all the DVR and other buttons.
Hmm, I just watched a show and though I would try it again, and this time it brought up the prompt about enabling notifications. After that, it worked just fine. Closing and reopening everything showed on first opens.
Something must have not set on one of the upgrades.
