Hello,
I have an issue on my Samsung Galaxy S21+ since the One UI 7 update.
The quick access icons and also the full dropdown menu icon disappears randomly.
When I restart the phone, the icons and buttons are there, but then after a certain amount of time, they disappear.
See the screenshots.
I am using Microsoft Launcher and I have tried to disable it in favor of Samsung One launcher, but I still had the same issue.
