No start session button on Maps

I have made campaign and have players join. Launch Maps and I can see the player in the token section and add them and monsters to the maps no problem. The problem is there is no Start Session button anywhere. The only button showing is the Display/Hide Scene button. Below is a screenshot.

The "Start Session" button was changed to "Display/Hide Scene" in a recent update as detailed here in the changelog

Thank you for your reply. My players tell me that all they see is waiting for the DM to start session. I've tried pushing the button to change it to hide scene and back to show scene and player reports there is no change on their end. Always the same message, waiting for DM to start session.

Are you and your players in the same campaign?

 Yes. When I'm in my campaign and maps, I can see them. They keep seeing waiting for DM message. Do I click Display Scene which switches to Hide Scene? By clicking Display Scene will this start the session?

Display scene displays the maps to the players. When the button says "Display Scene", your players will not be able to see the map.

Hide scene hides the maps from the players. When the button says "Hide Scene", your players will be able to see the map.

I just loaded Maps across two accounts and it shouldn't say "Waiting for DM", it should say "Your DM has hidden the scene."

The Display/Hide scene button worked fine for me, so I'm afraid I don't have any further suggestions

I'll try it. Thank you for your help!
