It put me here in Meta for no good reason. How do I navigate out of that and back into the regular eg medicinal chemistry or closest to it? I assume it's a bug in the system that put me here in meta? with no obvious way to get out.
The title of your question says "Beta" but the body of your question says "Meta". To get from Meta back to Main, you can click the burger at the top of the page, and then click on "Medical Sciences" which is next to a blue icon, as opposed to "Medical Sciences Meta" which is next to a black icon.
