Well finally bit the bullet and updated from iOS 14 to iOS 15.6.
First thing I noticed after it was done it was trying to update apps even though auto update is turned off and had to stop it from updating certain older apps that were installed with Apple Configurator.
(After stopped reinstalls there was only 10 updates)
Another thing is I have to keep resetting the cellular connection because it stops working, I hope this isn’t a bug.
Hoping I don’t regret upgrading. Was hoping by now they’d have the bugs worked out.
Update: Noticed my shared albums are missing. Hoping they reappear. It’s turned on in iCloud.
Toggling Shared albums in iCloud settings caused them to redownload to my iPhone. Whew.
Another crazy thing it’s doing is it’s installing apps I’ve deleted a long time ago so I have to cancel all the downloads.
Nothing has really been fixed with searching old messages. I can search for old 2011 messages and see them in the results but when you tap on it it goes to last message. It’s only when you tap on a 2016 or newer message you might see the actual text. That’s never been fixed since forever. I like to search/view old texts from my deceased brother and friends.
You know how when you get a notification and you press and hold on it to expand it in the notification area and there’s normally a little X to close it, it’s now missing an iOS 15 so you have to tap back out and then swipe to close it. Dumb.
On a good note Apple Pay works smoother, when changing cards it automatically returns to the double tap side button screen, before you head to press the back arrow.
Another positive, in messages when someone shares their location you no longer need to tap twice to see the little map, it’s on the first screen after you tap on their contact.
