Fail to fetch data from Cross-doc

Two days ago one of my Cross-Doc tables suddenly stopped syncing, and when I attempt to sync it manually I get the message: “Failed to fetch data from cross-doc”.

Other cross-doc actions are still functioning, it just won’t sync.

Any ideas?

It’s been not working for almost 2 days, and now it suddenly started working again. I didn’t change anything so I have no idea what did it. Will post an update later if I figure anything out.
