Just had this come up playing a game and I've had stuff like this also pop up on Facebook. Usually click bait I figure but found it be something trying to infect my phone?
I haven't seen that either. I'm curious to hear if you're only getting it in that app or elsewhere.
So far just on that app. I'll get things on facebook to if I do those quiz type things where it scans your profile to get the answer I'm told. Like for instance "Who's in your mafia family" Those kinda quizzes, I think its meaww and vonvon that offer them. It will say it wants to open something outside of facebook. I just close it all out and don't let it.
