My screen failed in my S21+ and the panel was replaced under warranty, however since the new panel was installed my auto screen timeout isnt working. The setting is set to auto timeout at 30 seconds. After 30 seconds the screen dims some but never goes completely dark to the lock screen causing my battery to drain. Any ideas?

Mine has been doing that as well after getting the charging port replaced. Now I have to physically tap it to shut of the screen. Like **bleep**?

At the time when you made that settings with the old screen, there are hardware communications between your phone and your old screen. Now that you changed the screen those communications are lost.
Try clear the e cache of not the data of UI home
If not wipe cache partition from recovery mode
If not backup and factory reset
