Text Message Notification Problem - Solved

I had the same question as User B3av3r about not getting text notifications from a user, and I believe I found the bug and solved for it and wanted to share the resolution.

I was not getting iPhone message notifications from one person, and Do Not Disturb or Hide Alerts were not activated. I would receive all messages but not get any sound or message indication alerts. The problem appears related to the Location Sharing in Find My Friends. Weird, but the problem existed when the other user was sharing their location with me and I wasn't sharing mine with them. When I started sharing my location with them, the problem instantly resolved itself. Hope this helps the other hundreds of folks who had the same problem....
