Personally, using dynamic updates is a bad idea.  It just fragments the OS even more with the potential for way more issues.  Why is your bootloader unlocked?  You really should relock it and leave it locked.  If you used TWRP to convert it, then you should have done it the right way, using the MSM Tool method.  Most users running Android 12 have factory reset their device to eliminate a lot of issues.  This is always recommended with a major OS version update.  

agreed. keep in mind that when these updates are being worked on and tested its on a fully stock device..no additional apps etc ..so taking it back to being as close to stock as possible tends to help..not everyones cup of tea..and wont help you avoid bugs..but its usually a smoother download.
