Does anyone know where I can find my navigation bar? Its disappeared from the left hand side.

Thanks for posting in the Community space, @info333.

I've answered the same concern to one of my previous customer. Check out the description below to learn how to find your navigation bar.

You'll have to click the Hamburger (three horizontal lines) icon beside your account name. That option helps hide and un-hide the left navigation menus.

For visualization, please refer to the screenshot below:

Let me know how it goes or if there's anything else you need. I'm still here to help you more.
