I had been happy with Apple for many years but encountered some really terrible experiences lately. There was a systematic problem on Apple’s side (related to the recent increase in iCloud subscription fees) and they cancelled my extra iCloud storage. To be fair they did give me a refund for the extra storage prior but I thought it was related to the pricing changes and didn’t think much of it. Other than that there were no warnings until the extra storage expired and they sent me an email saying the storage is full. I resubscribed immediately but iCloud mail could not send or receive anything for several hours afterwards, except for receiving emails from Apple.

I also have had several instances where iCloud Drive would take forever to sync. The most recent time got so bad (100% cpu usage that persists after killing the process when I added 5KB worth of files) that I stopped using it completely. Tried Microsoft OneDrive instead and it synced at good speeds and gave me no problems.
