At this time, I cannot make purchases on this site with the Mojave RC build of Orion.
(This repro might involve paying)
Repro steps:
- Log in to your Qobuz account.
- Find a song or album you want to buy.
- Click Buy the album then Finalize my order.
- Accept T&C then click Access payment at the bottom.
(after clicking that it gave me a Orion RC Networking quit unexpectedly while using the libwebrtc.dylib plug-in. message)
- Fill in your debit card details.
- Click 'Pay' and it'll show a error message:
SyntaxError: JSON Parse error. Unrecognized token <
Nothing happens after that and no actual payment occurs.
I did try on a clean profile and it was the same result.
Compatibility Mode did not work.

Able to buy music. Works as intended on the Sonoma build of Orion RC.
This has been happening for a while now, like a year or two ago.
