I upgraded from an S3 to an S4 (not planned but did it because of some eccentric AT&T pricing for a new shared data plan) and installed all my stuff, and now I don't get any notifications from Instagram or Twitter on my notifications bar. I used to on the S3 - it took awhile for Twitter to decide to work but Instagram was always trouble-free. I checked every setting I can think of for these apps and nothing is happening. Has anyone solved this and if so what did you do? The only solution I found via googling had something to do with going to an AT&T store and signing into Twitter on a Blackberry and changing your settings, which seems kind of a baroque thing to have to do... Any tips appreciated.... I can always try another Twitter client but I love Instagram and don't want to give it up.
