Unable to annotate others' shared content - latest zoom update

[Tdash]

I just updated my Zoom (Version: 6.1.5 ) and I can no longer annotate content that is shared by other people. I can only annotate when I am sharing my own content. I noticed that the zoom version before this one had a little pencil that would appear which would enable annotation. However, this pencil button as been re-integrated back into the regular Zoom nav bar in this latest version of zoom (6.1.5). I am on a MacBook Pro (Running OS 12.5).

I tried to to trouble-shoot by:
- updating to latest version of Zoom (Version: 6.1.5 )

- reinstalling the latest version of Zoom from the Zoom download center

- restarting my machine

- checking advanced settings for screen sharing / annotation (both on my account, and on others' accounts)

- testing calls with a number of other users 

Cannot find a way to solve this.
