Ok, so for the past few days I've been having some notification issues. For all the iOS stuff (Phone, texts, mail) the alerts come through, and some 3rd party apps (Tweetbot, WWF) also come through. But then I have a lot of other apps (CNN, ABC, Zynga Poker, Facebook) whose notification sounds don't come through. They all have sound enabled in the notifications list. I get the push notifications, I just don't get the sound. It's not muted because other notifications work. My tweaks are: Activator AskToCall Badge Customizer BiteSMS Blackout BrowseInApp BrowserChooser Calendar Pro for NC ChromeURL Cyntact DisplayCandy FolderEnhancer Gridlock ISX Jellylock Mail Enhancer Pro Multiiconmover Multistorey NCBettterSwipe QuickStore Springtomize 2 SwipeShiftCaret ThumbsUp BatteryDoctorPro 2x2 Folder Icons All the notification sounds work on my iPhone 4, and they worked on my iPhone until a few days ago. The only thing that changed since then was: Added: BrowserChooser, ChromeURL, Jellylock, Quickstore, and BatteryDoctorPro. Also, I installed Flusterless and used it for a day. Then I removed it. But i feel like the no sound started when I used flusterless to turn on DND (it is no longer on). I'm wondering if that might have corrupted any app that sent a notification while it was enabled?
