Incredibly frustrating, don't you dare log in on someone else's device even once because then they can't figure out how to let you log back into your own account. I let my boyfriend log into his account on my phone, thinking it would be no big deal as I had done that on his phone and he was able to log back in. Nope! No way to access my account any more and after 3 people trying to help me no progress. Incredibly frustrating after almost 2 hours with customer service and I'm actually crying.
