Numbers couldn’t connect to iCloud.
Hi.
I’m trying to collaborate on a numbers spreadsheet with another person. I invited them, they did a small modification, and saved. When I try to retrieve the change, nothing happens: I only get an error in the Collaborate tab “Numbers couldn’t connect to iCloud, You won’t be able to edit this spreadsheet until collaboration resumes.”.
I found a similar thread for Pages from 2015, but no solution there.
Thanks in advance.
