App works as intended (for the most part. I'll get to that). It works well on my phone. I also have the app on my tablet. Issue is, is when I have the tablet in vertical, everything works fine. When in horizontal however, the app freaks out and goes back-and-forth on having the codes in the center of the screen and on the left. Making horizontal useless.

The app stopped working on my phone leaving me locked out of my work accounts which I need the codes to get into. Edit: nothing weird happened before it stopped working. The app won't open past a blank white screen followed by an error message that says the app "keeps stopping". I updated, reinstalled, cleared cache and everything and it still didn't work. Edit 2: no, I don't want to have to download and sign up with another app just to get this solved.
