Safari Tab Group creation on Mac has become a total disaster, because Safari would immediately delete the group created on Mac with no discernible reason, only to find those empty groups appearing on iPad just fine. I have been wanted to move a Group of tabs from the same source to another one for a long time, but unable to.
Often times when I accidentally close Safari, ALL newly created tabs are GONE, GONE GONE GONE GONE GONE. It’s not being synced at all, more like server data being forced to override local data. Absolute terrible experience.
Notes iCloud syncing is also a huge mess. I need to restart notes app or even restart the device to see the changes if I am lucky.
Meanwhile OneDrive for Business has the Service Assurance guarantee for all of its users, works far more reliably than iCloud in terms of file syncing and such, version control is amazing.
I have give up all hopes believing Apple stuff “just works”, because it no longer does.
