Sorry to hear that you're having issues. I'm on vacation at the moment, but I'll help you as much as I can!
What exactly do you mean by "stops working" - does an error message come up, does it freeze, or something in between? If it's "freezing", does anything on the page respond? For example, if you tap the menu icon in the top-left, does the menu pop out?
An error message comes up, I can't go anywhere on the app. The menu icon does pop out, but it doesn't matter what I press the app doesntmove from there. Thank you, and enjouly your vacations.
