I've had my Sony Ericsson Xperia Play for a couple months now and it won't seem to notify me when I have new notifications in twitter, facebook, snapchat or instagram. It will show me that I have a new email or gmail notification in my status bar, but never for any of the previously mentioned apps. I've tried everything, i've synced and unsynced all of the accounts, i'v gone into the apps and changed the notification settings and sync intervals, and i even downloaded a extra notification, but nothing works. I know the phone is syncing fine because i still receive email and gmail notifications, and when i open facebook or twitter, for example, the notifications are right there, but they will not show in my status bar. When I first got the phone it would tell me when I had a new twitter notification or facebook notification in the status bar, but after an update it stopped. I would really like to fix this, that way I dont have to constantly keep checking these apps to see if I have a notification.
