Not sure when this started, but recently I've noticed my pixel 6a to not dim the screen and then shut it off as expected (tried 15 and 30 seconds) now and then.
For example, just as I'm writing this on the phone I'm experiencing the display staying active, after locking it with the power button it works again while looking at my posting with keyboard open, and after continuing to write the timeout is not working yet again (often reproducible as I just noticed while writing). This is only one situation where this happens though and it only started recently while I've been using GOS on this phone for two months.
I've read other posts about this from last year where this issue was supposedly solved (downstream error from android), but found not much else of help so far.
Ideas? Thanks!
