Apple Pencil Not Working with PowerPoint after Sonoma 14.4.1 Update

When delivering presentations, I use my iPad as an extended screen mirror and make notes on PowerPoint using my Apple Pencil. I have been doing this for years.

After upgrading to Sonoma 14.4.1 last week, I noticed this is not working correctly.

My Pencil is connected to the iPad via Bluetooth. When I go into PowerPoint Presentation Mode, I can annotate using my mouse on my monitor. But, I cannot annotate on my iPad with the mirrored screen on my iPad.

I have checked the Pencil...It is connected to the iPad.

I have rebooted the Mac and the iPad.

I have also noticed a similarly reported problem on the Microsoft site that sent the problem over to Apple. https://answers.microsoft.com/en-us/msoffice/forum/all/cant-use-apple-pencil-on-ipad-extended-display-for/c50c2378-c657-440a-898d-8bf838905051
