Hi IPATinc,

Random errors are probably the most frustrating to figure out - even for Tech Support.   Understand that the Community is not the same as Tech or Customer Support as most of us are much better at running small businesses, using Square's Apps and Hardware.  Unless someone here has experienced the same type of issue and was able to resolve it, we probably don't have a clue as to what is going on especially if you can't reproduce the same issue.  Note, there are times when Square's Systems have issues and can cause various problems for some of us or all of us - that's where this link comes in handy.  We've learned that when ever an issue pops up, the first place we check is that link.  It's helpful for narrowing down the problem.  If you're not already keeping notes on issues when they pop up, it's a good time to start.  Doing so you will have better details for Tech or Customer Support.
