When I leave the Verizon Message+ application in a conversation new messages received only briefly so as a visual notification and then disappear. I do not receive a vibration or audible alert for the notification either. This is causing me to miss messages on a very frequent basis.
I'm using Message+ 6.3.5.
MAKE SURE IN SETTINGS A TONE IS SET FOR NOTIFICATIONS AND MAKE SURE SETTINGS ON EACH SIDE OF APP HAVE ENABLED. LOOK UNDER CUSTOMIZE AND ON LEFT UPPER SIDE NOTIFICATIONS ENABLED IN SETTINGS
