Are you adept at phone screen thumb clicking?

So, I was trying to show my banker that their bank app wasn’t working. Really. It show a white screen only. So, I thumb clicked on the bank app, turned my phone around to show the banker, but the look on her face was more perplexed than mine, so I turned it back around to see what she saw… It was my SW login page instead! Now, how did that happen? Lol don’t worry folks, it was just a plain login page, no profiles shown. I was tempted to have her wave and say hi to all my friends here. :-X
