To enable Apple Pay on one of our third party softwares, a Verification file needs to be uploaded to a particular path in the CMS without the extension.

Here is the requirement "Place this domain association file in the /.well-known/ directory. The full path to the file will be https://mycharity.com/.well-known/apple-developer-merchantid-domain-association (where mycharity.com is your organization’s site)"

So whenever we try to upload the file to the above path the extension ".bin" gets added to the path.
