I only have one location set which is Australia. I tried using this and 'All Locations' to no avail. The test account I am trying this out with has an address in Australia. There is only an 'address' setting for customers not a 'location' setting so I'm assuming these match if I have Australia as the customer country and Australia as the 'location' of the extension. Although the Paypal extension is set to 'All Locations' and it works fine, just the Bank Transfer extension is not showing at all no matter what I set 'location' to.
To test I also set up a Paymate account and added to Paymate extension. It also does not show. So then I thought I'd disable the paypal extension to see if it was causing the issue. When i do this no payment method shows even when the Bank Transfer and/or Paymate extension is enabled.
I then set up paypal express and enabled it. I can then see both paypal and paypal express options but no others.
I also tried with the COD payment extension, it also didn't show, still only paypal.
How can I debug this to figure out why?
