Does anyone else have account problems with the app?

This morning I was playing a few Valentine Events, but then I pressed the HOME button on my tablet, waited awhile for my stamina to finish up, but then when I clicked on the Skullgirls app again, It logged me out of my actual account automatically and said I was logged in as a guest. Has this happened to anyone? Is it a common problem? I tried to upload an image of it but this site kept saying "an error occurred."

I've had a similar issue happen to me a couple of times. Where when I start the game it randomly logs out my associated Line account and just shows the play button at the start (like when you install the game for the 1st time). But then I logged in again and everything was fine and none of my progress was lost.
