No.Never been online not even wifi setup. Should be ok after factory reset?
Everyone screaming "YOU WILL BE BANNED NO MATTER WHAT DOOM AND GLOOM IS CERTAIN RIP YOU" has no idea what they're talking about. I played around with FG when it first came out, a few times a couple weeks later, and tried SX OS when that happened. I've spent the last two days straight playing Fortnite for a few hours. No ban.
I'm sure tomorrow I won't be banned either. If you have done the research you would know most people banned has been from using devmenu or backup loading though LayeredFS or SX OS. So GTFO troll and stop miss informing people
