Collectible Card Game Headquarters

Hello, I recently downloaded forge and first I should say that I love the app. It's amazing what you've done with it. I've been testing out some of the variant formats against the AI and I started trying commander today. Everything runs fine in the match, but I can't figure out how to cast my commander as there doesn't seem to be a window for the command zone.

There's a button on the side near the floating mana for the command zone. I think you can also use the "flashback" icon to cast a card from any zone other than your hand.

I'm having an issue getting my decks to register as commander. I've got all 99 cards in but can't for the life of me figure out how to set my commander. Been putting it in the sideboard, but obviously that's not working. Any help?

So I figured it out. Kept seeing "check constructed and click commander" which made no sense to me on the mobile version. But when you go into deck manager there's a drop down window up top that you select commander on before hitting "new deck"
