Well 13.1's supposed to hit in three days. Let's hope it fixes this bug, as well all the others people seem to be experiencing with this POS release.
I just noticed the Mail app no longer checks for new mail now until I launch it. No matter than I have it set to fetch Gmail every 15 mins, and iCloud is set for push. No new mail if I don't open Mail and let it manually fetch. So iOS 13 = manual mail fetch.
The MAIL app. And nobody at Apple noticed this before they released it? Nobody at Apple uses the Mail app? Do they all communicate to each other internally with animojis in Messages?
And anyone try to sync their Music app from their phone to their iTunes playlist over WiFi? Can't find that button anymore in iOS 13? Search "Sync Library" in Settings. Ahh, there it is. Tap on it. The link's there but the feature is gone. Not there anymore. Only way to sync now is with a Lightning cable, or over WiFi but you need to do it from iTunes on your Mac. Which is going away soon with Catalina. But hey, anyone still syncing actual music files anymore is a fossil. Better to pay every month to lease your music from the cloud and burn through your data at the same time. Progress!
There are dozens of other major bugs in this release. First time I've ever really been burned by updating my device on day one. I used to laugh at the old timers who waited a few revs before updating to a new iOS. I was wrong. Listen to old people. They've seen what happens when a suit who doesn't even seem to use computers himself takes over a company that makes computers.
