Acrobat Collaboration Synchronizer energy consumption

M3 Max MacBook Pro, macOS Sonoma 14.5

Earlier this morning I shared a PDF document for collaboration using the built-in Acrobat DC feature.

Even after closing the document (with Acrobat still running), the Acrobat Collaboration Synchronizer process was using between 150 and 200% of CPU energy. 

I used the AppTamer application to put a limit on it when Acrobat was not in focus and it helped but I believe this should have not happened in the first place.

More worrying, though, is the fact that:

1. the process should not be running if the shared document is not open

2. the process should not be running if Acrobat has been quit!!

I have been obliged to Quit the process in Activity Monitor to prevent it from using resources best needed elsewhere. 

Please fix this kind of damaging behaviour as soon as possible.
