These bugs happened with iOS 9 as well as now 10. If I send three iMessages to someone, and they have their read receipts turned on, it says that all three were read. Then a few hours later, when I return to that message thread, it just says the first two were read and the third is still sitting at "Delivered." If I switch to my MacBook Pro, it says that all three were read. In my Notification Center, if I have four unread messages, for example, I can view them for a limited amount of time in the NC, and then they disappear somewhere along the way. 30 minutes after I checked NC the first time, all of my Messages notifications have disappeared, even though I haven't actually opened the messages. If I want to "Clear" an email notification from NC, it sometimes won't. It's about 50% won't, 50% will. If I have any others, I will post them here. Do any of these happen to you guys? I just restored from an iTunes Backup to my brand new 7, but I was thinking about doing a completely clean install and starting fresh. Do you think that would fix these bugs?
