This package has some debug code to give info on what is happening. You can deactivate/delete your existing Patreon WordPress, upload and activate this package above.
Then when you visit ‘Patreon Settings’ -> ‘Site Health’, you will see some debug info printed out at the top of the page. Copy/paste the portion from the top until " Health check of your Patreon integration" title down below, and DM me via the forum. (or, mail to ozgur@c.patreon.com)
That debug info will help track the reason for this issue.
