New LrC Collections are not Sync'ing

[Alexandra272476918oyz]

The LrC collections I have created since upgrading to v12.0.1 are no longer sync'ing with LR mobile (I'm running MacOs 12.4).  

And I can no longer see the 'sync with Lr' checkbox when I'm setting up collections.  Any idea how to fix?

Collections can only be synchronized from a single catalog. Is it possible that you have opened a catalog other than the one you have chosen to synchronize from?

Hmm, could be, thanks. I have a vague memory of being asked to set up a new catalog when I upgraded to this version.  How do I find out and switch to syncing from the new catalog?

[JP Hess]

No, creating a new catalog as a result of upgrading your LrC wouldn't result in causing the problem. The problem would present itself "if" you had a catalog that you initially began synchronizing images from and then started a separate catalog for some reason that you wished to keep images separate from your "master" catalog. Those images in the separate catalog would not be able to be synchronized. Only the images in the master catalog would be Synchronized. This would remain true even  after a version upgrade.

Ah no, I definitely haven't created a separate catalog, I've only got the master

Is your catalog still synced? Look at the cloud icon in the upper right corner, next to the modules. Does it have a green checkmark?
