Beware of Logging in From Multiple Devices!
I am hoping this was an automated response from Kabam and they will sort it all out, but want to save some of you any headache.....
I run an S7 Edge as my main driver and recently started using an old iPhone 5C with a broken mic as my gym phone so that I don't get my nicer phone sweaty and gross. I put MCOC onto my gym phone as well in the last couple of weeks, as there was some communication and crystal claiming I needed to do while in the gym.
Today I forgot my S7 Edge at home, and it wasn't a gym day so I didn't have my second phone with me. I manage our company's devices, so I grabbed an unused iPhone 5C at work to use for calls and texts throughout the day, and I downloaded MCOC onto it so that I wouldn't miss out on any free crystals and could still eek out a couple quests during down time. I then went to log into my account from this third phone and received a notice that my account has been permanently banned for a TOS violation.
All three of these devices have been used within a 30 mile radius of each other, and I have not cleared any significant content or done anything with my account (aside from buying the Medusa offer on my gym phone) on the two iPhones. There has also never been anything done with my account, ever, that would in any way be considered a violation of TOS (no sharing, mods, hacks, rewards exploits, etc.).
TLDR: Don't log in from multiple devices if you don't want to spend time sorting out a perma ban!
