New bug app and Infotainment systemwith myGMC

Looks like GMC has created another bug for the infotainment system. About a month ago I started to have issues with the audio on the display. No radio or sound. Press audio and nothing happened. Tried all sorts of things, but no go. Took to dealer and showed them the issue. When logged into system using guest, everything functioned correctly. When I logged into my user account, audio did not work. Dealer was puzzled too, so left truck and they went to work trying to figure it out. What they were able to do was update to v810 and added a couple of other updates too. This did note fix issue and dealer did not have an answer. Tech did think there must be a hidden setting out there that we could not find. Next day after thinking about the issue, I remember the myGMC app had a major update around the 1st of June and that's when all the bazar issues started. Solution was in the app. The app has a bug in the "MEDIA" tab. When selected you have a choice off adding apps or favorites with your xm, fm, and am radio setting. I found mine with a whole lot of fm band stations set as favorites. I never set those up and only had one station saved on fm on infotainment system in the truck. I deleted all saved entries on app until it came back with a screen the said " you have 0-40 favorites available ". This screen also blocked access to xm and am selections so there is no way to look at the settings without adding a favorite to the selection screen. Went to bed and got up in the morning to do some shopping. Started truck and logged into my user account and low and behold, audio now work. Also found that I could not add app from infotainment screen in truck, but I could from myGMC when I used the media tab. Looks like to me the "Media" tab in the app is broken. Showed dealer and they were baffled too. This happened on a Apple iPhone with the latest ios update from earlier this week. I suspect all the mychevy, mybuick as well as the myGMC will have this issue.

Latest updates done on my 2020 GMC Canyon Denali. Any information or a link to what's in these latest updates. So far other than app issue reported earlier, infotainment has functioned well without a hiccup. Cannot find a TSB for V810 update. The other 2 would be nice to know what they addressed and or added. I did see a hill decent message on center display screen which I have never experienced prior.

Anyway more info on these updates would be nice.
