notifications
when i'm on other social media for example facebook i do not get notification from snapchat
it used to show up at the top of the screen but now I get nothing, what should I do?
Most likely, this is an issue with the Snapchat app or its configuration. I'm sure you have already verified the notifications settings on your iPhone for this app ... correct? If so, and they look correct, then you may need to contact the app developer for additional assistance with this matter.
