Trouble Adding Money To My Apple Cash Card - Possible Quick Fix

I have always had trouble adding money to my Apple Cash card...I always received this message: ""Apple Pay Services are currently unavailable. Please try again later."...I tried adding different cards with no success...Finally, I called support services and was on the phone for about an hour...we tried several things with no success...my call was even sent up the ladder to the next level support tech...still no resolution...it then dawned on me to ask the question "The debit card I have added on my phone is a MasterCard business debit card, could that be the problem?"...the technician then told me that for some reason MC business debit cards don't work...I put in my personal debit card and everything worked fine...I suggested they make that one of the first questions asked - "Is this a MC business debit card?" - would've saved a bunch of time and months of not being able to use this feature...hope this helps someone else 😊.
