Watching DIRECTV

The enhanced menu Pop-up notifications are unwanted. How do I disable these messages - annoying, unwanted, and they disrupt functionality. 

Which HEDR format Does DirectV use? Is it HDR10, HDR10+, Dolby Vision?

When I use the jump back function (the button with the reverse semi circle arrow) my show freezes for a few seconds. This just started yesterday and it’s a big deal for me as I use it often. Any ideas?

Is there a way to select My Teams under the sports central? The old menu let us select our favorite teams so it was easier to see when they play.

When I try to delete a recording I get "please wait" and it locks out my remote to where I have to turn off my TV. Please help

Picture comes in and out on my favorite channels but not on all channels. I checked all plugs. I read directions to turn it off at the green button but mine is blue. I unplugged it for 30 seconds and it still does it!

I have Peacock TV with my Xfinity account. Can I access it on DirecTV without buying a separate (second) subscription to Peacock TV?

I don't see a way to view my list of upcoming recordings by day or my list of series set up to record. Has the ability to access those been taken away?

Receiving the above message on channels 355 and 570 only, both important channels to me. They work when switched to internet but this drives up my internet bill.  How do I fix this?

I have Starz with my DTV subscription and was able to login to the app on my smart tv a few days ago using my DTV credentials. For some reason, I can no longer log in.  It says "you are not authorized for Starz service".
