These were all intermittent: Messages were lost or delayed for very long periods (going both ways), groups were completely broken, I couldn't tell who was messaging me because they were assigned some random source number (which I think also happened both ways), and images were compressed to illegibility.
Some people I seemingly just couldn't text with at all.
Here is just one small thread of thousands about it: https://discussions.apple.com/thread/6750172 [Not the best example, but I'm having trouble tracking down the posts I remember browsing back when I made the switch.]
It was a complete mess, experienced by many users, and it was entirely Apple's fault.
It pains me to think how many friendships and romantic relationships might have been crushed by this bug. Neither party will ever know why.
I really don't understand why you think it's relevant today.
Which is exactly what should have happened.
Examples from personal anecdotes include:
- My first Macbook pro several years ago was the cheapest one at the time, and basically got stuck in a boot loop when I opted out of creating an apple ID on setup. Needed to boot into safe mode and factory reset it to start again.
- Setting up an iPad (in the last year) for a first time iOS user, required two 2FA challenges and needed the apple ID password ended no fewer than 7 times in the first 5 minutes of operation. The App Store didn't work for a few minutes for reasons unknown, and then with no changes, started working. (I'm guessing the creation of a new apple ID takes a few minutes to propagate to the app store or something?)
I'm sure everything goes smoothly when you just log in with an apple account and import all of your existing settings from iCloud etc, but if you're jumping in for the first time and press the wrong buttons it's rough!
