@lostfocus Can you elaborate?

I'm getting {"error":"invalid_grant","error_description":"Failed PKCE Validation"} with an HTTP 400.
It's probably something weird happening when creating the code challenge on the non-WP-side. I'm not sure yet, though, I just got back home today.

@lostfocus I recently fixed a bug that if you were using PKCE, it wasn't properly passing the PKCE parameters for validation, so it was treating it like no PKCE. Could be it never really worked.

Yes, it's 99% likely a client issue and not one of this plugin.
