Cannot utilise keyboard shortcuts while typing

Hi all,

I am trying to utilise keyboard shortcuts whilst typing in sticky notes on Adobe Acrobat Reader DC on macOS Monterey. I cannot for instance press Command + B while typing and then the text after that will be bolded; instead, I must rehighlight the text and use that command, which is really tedious. 

I have tried using the solution proposed on another thread (https://community.adobe.com/t5/acrobat-discussions/acrobat-dc-keyboard-shortcuts-not-working/td-p/9964681) which suggests enabling Use Single-Key Accelerators To Access Tools, however I have not found this to work.

What else can be done?

Thank you
