When I'm on app at random times it will open to a site that gets blocked called go2click it's some suspect Survey site.
Random Opening to Survey Site
I also have something similar happening when I'm reading it ask me every 5 minutes or so what webrowser I want to use and it doesn't stop I've visited the site it wanted me to visit oh so badly and just says its not available in my area like banner ads on fanfics were terrible but now its forcing open my browser to show me what I assume is to be that survey your talking about it started happening like 5 hours ago
I'm having the same problem and for me it started with the last update
Ya it's getting real suspect im thinking the app or something was hacked.
