Worthless app. Constant 500 server errors.No help from cus support.. answer 2 months after questions. Say they are overwhelmed with messages, but somehow manage to post bills before you leave the dr ofc.They wiped off all past statements. All you can find is current one and of course , balance due. But if you are wanting anything else, forget it. Going back to paper billing so I can have copies. Wont bother with this app anymore.
