Shared folder disappeared from all devices
Both I and my wife have iCloud accounts. I created a folder in my account and shared it with her email address/account. She has several Apple devices and normally the shared folder shows up under iCloud Drive (path iCloud Drive/Shared). Everything has always worked until yesterday.
Yesterday, the "iCloud Drive/Shared" folder disappeared from ALL her devices. I still see it in my iCloud Drive, with all its contents, and it still shows as being shared with her.
Initially it looked like the folder was completely gone, and this highly troubling regarding the reliability of iCloud Drive.
Since on my end iCloud Drive still thinks the folder is shared, I can't re-share it, and am hesitant to take any action lest the folder disappear for good. I'm making a full backup of the 12GB in a local folder on my computer, but given that only about 10% is locally cached this is going to take 7-8 hours.
How do I recover from this.
