I cannot create a game

Hello. I just downloaded the app.  The only 2 options I get when I login are "Logout" and "Join game". The app will not let me create a game.

The App is different from running or creating a game. The App is designed to be a play aid , allowing you access to character sheets, handouts, and dice rolling. It is not Table on Tablet , a feature for Plus and Pro subscribers.

Oh okay.  So, someone with Plus or Pro can create a game and I can then see it?

The links I gave should explain everything. If you or someone else creates a game and you are a member of that game, you can log in with the App and see character sheets, handouts and roll dice, but you cannot see the map or move tokens. If you want to use Table on Tablet (not an app, just using your mobile browser to play in a game on Roll20 as if you were on the desktop), you need to be a subscriber, regardless of who created the game.

Thank you.  I appreciate your help
