Remember that when you subscribe to any tier, you should automatically get access to the Discord server, that’s where all the full content is available. On Patreon (and SubscribeStar), I only post cropped previews of the illustrations to avoid any issues with the platform.
If you haven’t been able to join Discord yet, try these possible solutions:
Make sure the email you used to subscribe on Patreon is the same as the one linked to your Discord account.
If that’s already the case, a good option is to log out of your Discord account and then log back in.
If this still doesn’t work, it’s likely that your Patreon account isn’t synced with your Discord account. To do this, follow these steps and then restart your Discord login: settings > more > connected apps > Discord > connect
