normal transaction not registered in list

[roberttherolfer]

Forgive me if this covered in another thread. I succesfully completed ( I thought) a manually-entered transaction a few minutes ago. A brief Square error message showed up on my iPhone, after the client left, saying something about the transaction had not been completed. I found several error messages, saying that transactions weren't completed that had been, but today's is not, apparently. At least, this recent one is not showing up yet. Obviously I will call the client if I have to, but the card entry was smooth, and it was not declined. I just sent a query to Square, but...any ideas out there about what else I should try?
