Charging problems using a monitor output since Tahoe

I’ve been charging my macbook pro M1 for the last 2 years using the powered output from my monitor. It’s worked perfectly. However since updating to Tahoe this seem broken. It no longer automatically charges, I have to unplug and replug and today my laptop wouldn’t start this morning as it had run out of battery even though plugged into the monitor?

Is anyone else experiencing this? Is there a fix?

You are not alone… seeing the same thing using a dock.

Charging through a CalDigit TS3 dock, and I didn’t notice any issues.
