Same exact issue here with Spotify OAuth. Similar behaviour to the above. It goes through the Spotify login fine, asking for user permissions and redirects to my iOS app but I get the error:
I/Capacitor/GenericOAuth2Plugin: Authorization failed with The operation couldn’t be completed. (OAuthSwiftError error -1.)
ERROR MESSAGE: {"message":"ERR_NO_AUTHORIZATION_CODE","errorMessage":"ERR_NO_AUTHORIZATION_CODE"}

same, I'll try reading the actual ios code and following how the oauth flow should work, it seems that its just a curl call
