"Using Go+ notification to open game causes black screen."

#PokemonGO: Don't know if this is a known issue, but I don't think I've seen anyone else reporting this in the past few weeks. I have a Galaxy S 7, using android version 7.0.When I catch a Pokemon or spin a stop using the Go+, it gives a notification saying that I caught a pokemon or got x items from the stop.Then, if I click the notification, it's supposed to open up the game. However, I find that many times it fails to do so, it "opens" the app but has a black screen. If I leave it, it seems that the Go+ actually remains active and continues to do its own thing, finding stops and pokemon, and actually will spin/catch them.However, if I try to then go back into the game, the app restarts.Anyone else have this issue? It's pretty annoying, because then I have to go through the 5 minute ritual of trying to get the Go+ to connect. via /r/TheSilphRoad http://ift.tt/2y5dLG3
