Guys, As the title says, the left hand toolbar is completely missing, and the screen displays "No map selected." I have tried diffrent browsers, I have cleared my caches.. I have even tried diffrent devices. Nothing seems to work.

Any idea how to fix this??

You don't choose maps from a lefthand toolbar. There's a Select Map drop-down in the top menu.

Also ensure you are the DM - only the campaign DM can choose the map.

 Nope, thats not working either.. Also yes, I am the DM of the campaign...

Then try a different browser, check VPNs, extensions, device, etc.
