Bring back iCloud support
Ok we get it, you are really happy with your new cloud service. However you should still give your users the option of using iCloud over your own service. I have been a Day One user since 2013 with zero issues while using iCloud sync across multiple devices. Now I am forced to create yet another account, which in your eyes is more secure, but in my eyes it is one more service that could eventually be hacked.
