In my use case, I have to turn off my primary which is an OLED to keep the screen working well. This is also why I lock the taskbar to the second screen. 

Win 11 Version  10.0.22621 Build 22621

Steps to reproduce 
1. Unlock taskbar from primary
2. Move taskbar to secondary monitor
3. Lock taskbar to secondary
4. Turn off primary monitor. 
5. Turn on primary monitor
6. Taskbar moves to primary, but I want it to stay locked on the secondary monitor.

You can also set the secondary to Primary display then changing the primary display to the original primary will move the locked taskbar as well, Even though it should stay locked

Anyone have ideas on temporary workarounds until StartAllBack fixes this?

Did the latest update address this?

No, sorry, this is not an important scenario.

Been having this issue too. Wasn't sure if it was related to PC sleep/wake, but it does seem to be related to the monitor standby. I think this is kind of an important scenario, given how many folks are using SAB to move their task bars to a non-OLED secondary monitor to prevent burn in.
