Applications tend to be a troublesome bunch. Sometimes, you get unlucky, and a bad update installs on your iPad. You might have something like Chrome keeps crashing.
What do you do? Close the app completely! The iPad keeps what we call a cache to launch recent apps quicker.
- If you have a new iPad or iPhone with no Home Button - swipe up from the button and pause in the middle of the screen.
- If you have an earlier iPad with a home button - double-click the home button.
What this does is that it force quits the app and clears it from memory.
If the problem persists, submit a support ticket.
