I get this weird message in my phone that's at the bottom of my screen in a green box. It says something like "We can't complete your request right now. Try logging onto the network rather than wi-fi." Or something like that. This has never happened before but now it happens roughly once an hour. It never happens when I'm actually using wi-fi, so there's that weirdness. It does occur a lot when playing Pokemon Go, though that could just be because that's most of what I do with my phone. It also has occurred when Go is off.
