Yeah, I noticed that thread right after I made mine.Yes, there is a thread dedicated to this in the iOS13 beta thread. I myself had the same issue as do tons of other people. There is no fix right now outside of waiting for another beta or removing the beta and going back to iOS 12.
Yes I have always fancied signing up and getting my hands on software early through betas, but it’s things like this that put me off.
It's because the Developer Preview and Public Beta releases are not early access to the upcoming software. It's beta. It's buggy. It's inconsistent. It's (primarily) for developers to test their apps against the new version. Too many people just hop on the train to get access to the new version early. They are often sorry they did so. (Not making any assumptions here, just a generic "caveat emptor" kind of disclosure.)
And to keep this on topic, to the OP, yes... plenty of people have complained in a number of threads. (Forum Search can come in real handy sometimes.)
