Credit cards not processing through appointments app

[Stressaway]

Hi I’ve been having a little bit of trouble with some credit cards not processing through the appointments app. Anybody else have this problem ?

Hello @Stressaway! Sorry to hear you were having trouble with the Appointments app over the weekend. So that I can help can you let me know a bit more about the issue you were experiencing? Can you also let me know what reader you're using and what kind of mobile device you have? Happy to investigate this further!

I have a client who has paid online thru the scheduling app which is linked to square, and all of a sudden her credit card will not process. She tried a few times and even tried another credit card. Please help- frustrating for a good client!
