Twice it has completely erased my list

When it works it is fine. But here i am on vacation and my list of 20 stocks has completely vanished and i do not know why. The first time it happened i had added one more stock to the list and it erased everything else. This time i was not making any changes the entire list just went blank leaving only one entry.

Not reliable is a dealbreaker for me.
