I am on the Pixel 7 Pro, I have the "Settings > Security > "Enable Secure App Spawning" Enabled as I have never disabled it. I am trying to help my uncle get myQ working on his p6p and he had issues until reading this thread to disable this feature.
I am posting to express that this may appear to fix it but there must be a different issue as it works flawlessly on my p7p (google profile-3rd/profile) when keeping the feature enabled. If this thread ever continues I am willing to help on my end if there is anything I can do.
