My always on display is not working and I am on the One UI 2.0 Beta I do not know what to do to fix it.
I'm not sure if I'm on the Beta (I'm not a techie) but I have an S10 & did the most recent update a few weeks ago and I just realized this morning that mine doesn't work either. When I went to my settings to fix it, I don't even have the option anymore to turn it on (it's grayed out). I'm very upset, as I use the edge clock at night so I can quickly see the time if I roll over in my sleep or something. These past few weeks I knew it was something weird about me having to actually tap my phone screen late at night just to see the time...it just clicked this morning that AOD was gone. :-/
Are you using an AOD theme or a theme that has an AOD screen installed with it?
Actually - I just realized that I didn't have the option to turn on AOD bc my phone was in power saving mode, which I did not turn on. So maybe that was automatic with the update? Either way, I've figured it out now!
That is definitely weird but I am glad you are back up and running!
