Apple Pay failed: Page already has an active payment session.
Currently, I'm developing a web service that provides Apple Pay functionality, so I'm trying Apple Pay Demo on this page.
https://applepaydemo.apple.com/
And I found that Apple Pay failed on a certain device with the following error message.
> InvalidAccessError: Page already has an active payment session
I'm using:
- MacOS 10.14.6 (18G84)
- Safari 12.1.2 (14607.3.9)
I searched for some information but couldn't find anything useful. I also checked WebKit source code, but still not sure what's wrong.
Does anyone have an idea?
