Hello,
My problem has started out just recently. I am one of those people who upgrades their phones every year. I am also responsible for the devices of my parents including iPads and all. With our switch to 18Pro, I started out having problems with the devices. I have recently switched my work phone for a Duo and the problem is still there.
When I try setting up a device using another device to make it easier - I simply have an issue where it keeps trying to login to my Apple account. The circle keeps looping until forever.
Then I reset the device and boom, we are in. But I waited for like 2 hours for once.
Trying to pick a back-up from iCloud brings in the same problem. I don't see the backups, it takes forever to download, I reset it and all is good. Sometimes the devices stop responding all together.
Setting up the wi-fi is the same.
When I called in Apple Support, they simply asked me to set up the device without an Apple ID, but that's not solving the problem for me.
They thought that it wa say wi-fi that's the problem, but I believe it is something else as my connection is super good. But just in case, I have purchased a USB-C to Ethernet cable just so I can do things faster. All those problems happened yet again, today - as I was trying to set up Duo.
I had all these issues, was able to find the right back-up -- backing up has started and stayed like that for ours. I tried logging on and off with the wifi and lan. Then I just erased my wifi info and set it up yet again and boom it started syncronising with iCloud.
I kind of had the same issue setting up the user accounts on my Apple TV. It took a whole afternoon to introduce everyone's account to the Apple TV. I believe this has something to do with my Apple account / log-in but I can't seem to get the help from Apple.
I am on a 6TB tier on Apple iCloud plans - and more than half of it is currently empty -- I also had an issue with my iCloud Photos synchronizing with my devices. That sort of solved itself after hours of talking on the phone w/ Apple but somehow they don't know what they did and I haven't done anything extra.
I consider myself a heavy user with good knowledge but I just can't solve this one.
Has anyone ever experienced anything like this?
