Not working after Jan/2016 update – Flint - Accept Cards, No Dongles. Invoicing. Review

App stops working after new update. Customer Service reports no issues on their side or any problems with my account. Transactions did not go through with Flint but went through with my back up credit card processor so no issues on my side. Hope they can fix the problem soon.
