I have two instances of the same page open in two different private browsing windows. In one, I am able to successfully see the page’s content after confirming my Patreon credentials. On the other, I receive the mismatched URI error I have seen others describe on here. Here’s the error, just for completeness’ sake:

{  
“error”: “invalid\_request”,  
“error\_description”: “Mismatching redirect URI.”,  
“state”: “YToyOntzOjE4OiJmaW5hbF9yZWRpcmVjdF91cmkiO3M6MTA0OiJodHRwOi8vYXJjaGltZWRlcy5zdGFydGFsa3JhZGlvLm5ldC9hbGwtYWNjZXNzL2ZpZ3VyZS1za2F0aW5nLXBoeXNpY3Mtd2l0aC1vbHltcGljLW1lZGFsaXN0LXNhc2hhLWNvaGVuLyI7czoxMzoicGF0cmVvbl9ub25jZSI7czozMjoiMTdkODExNTYyOWViYjViMzZjMGY1MzMwNzNiZDg2MmQiO30=”

This is odd.

Can you try by logging in with the user which has the issue from another browser window. WP’s stateless login mechanic may be getting confused.
