The top left Campaigns panel lists all campaigns you own or have joined. There are two buttons available for this panel, Clone Campaign Data and New Campaign.

Clicking a name in the Campaigns list will take you into that campaign. Next to the name is the current player count, followed by the subscription tier. If the subscription tier text is green, it is active. If it is red, something is wrong with the subscription and it is inactive. If you are the Game Owner (you created the campaign), you will see a small crystal icon. If you are a Game Master, you will see a small "GM" symbol.
