Starbucks top up Apple pay says wrong billing address
I have Apple Pay setup and works fine here in UK on my iPhone 7+. I use it in shops with contactless all the time and all ok.
However today I went to top up my Starbucks app via Apple pay and it says when authorising with touchID that my billing address is wrong, it's highlighted in red.
I check it and it's all ok, it must be as works in shops etc all the time.
What is wrong here, Starbucks or the Apple pay? So I can email support to help.
Thanks
