Did you used to have access to the Member Channels on Discord but can't see them anymore? If you still have an active subscription, there's a chance they just became unlinked. This shouldn't happen but sometimes accounts can become unlinked.
Please visit your membership page by hovering over your profile picture or account name in the top right of the screen, then selecting Profile. Once this screen loads, click on "Membership". You will see a red box that says Disconnect Discord:
Please click this button to disconnect, and then clicking the black Connect Discord button after.
This should fix the issue. If the issue is still there, please contact support@plomastermind.com for additional help.
