Zoom cannot refresh calendar integration

Help
1

Hi there, running Zoom from unstable on Gnome. All works great except the calendar feed on the home tab. It states there are no events scheduled (there are), and also periodically presents a pop-up that says:

Your calendar couldn't sync.
Meeting and calendar services are temporarily busy. Refresh or try again later.

[ Refresh ] (<---- button)

Has anyone seen this or come up with a fix?

Cheers.

Can you confirm that the issue isn’t with Zoom services?

It works without issues on Ubuntu and Mac – just not NixOS. Side by side.
