Apple Pay UK 'no location available'

In my experience, the location for the transactions is usually determined using either data from Apple Maps, or GPS data if the merchant is not listed in Apple Maps, so there may be times when the system can't determine the location where the purchase was made and will say 'location not available'. I've had that happen a few times, as well as a few incorrect merchant names, and there's not much we can do about it. The only thing I can suggest is to make sure you have location services enabled for the Wallet app. Other than that, you can tap on one of the transactions in the list and then on 'Report an issue' and see if you can report your issue. In my case, I have gotten an error every time I try to report an issue with a transaction, but I believe it may be because I am using Apple Pay in an officially unsupported country (Mexico), so I think you might have better luck reporting your issue since the UK is already officially supported.

That could be a software issue with the banks in the UK. As far as I know, if your information is correct in your Apple ID and in Wallet for your card then there is no issue on the Apple side.
