android app keeps crashing

[scottbaste]

the app was working fine for months but just recently, it keeps crashing the tablet.  we are running tablet with android 6.0.1  removing the app stops the crash but reinstalling it causes the tablet to constantly restart

I am having the same problem. Worked fine yesterday...this morning it would just flicker. I uninstalled and re-installed, now I can't even sign in. Everytime I try, it goes back to the main sign in/create account screen. I'm entering credit card sales on my computer browser, and they charge a bigger percentage when you do that.
