Hi I’m struggling to connect my new credit card to this app. The credit card company is called “Capital on Tap” I need some help transferring the transactions across!

I have been in dispute with the Capital on the Tap team as they have looked into this connection issue and seems fine at their end a numerous amount of times. I am currently with starling bank for my debit account and I have zero issues with the quickbooks application however this is causing me a lot of frustration now! If possible can you connect my account? Kind Regards Dan
