Impossible to change Patreon user in iOS app

I don’t think it’s possible to evict cookies of other websites. But we have other options here

  1. From your Patreon account page https://www.patreon.com/settings/account you can unlink the Discourse app which is wrongly connected.

  2. While sign-in again using Patreon in /oauth2/authorize page where you will be asked for either “Allow” or “Deny” the permissions, click the “Terms of Service” and logout from Patreon in next page. (yes they are missing “logout” / “switch account” link in authorize window)
