Strange. I thought I’d read in anther post that something major was moved to another location. Try the gear icon just above and right of the workspace window, or any other buttons that you aren’t used to seeing.
Since I believe this is a beta feature, you will want to look for the beta features section.
The button for beta features is located in the File tab. One of the beta features should be active for the new studio UI.
I apologize for the very late review, I was away from my computer for a few days. I had to reinstall Roblox Studio for the issue to be resolved. Thank you guys for your help.
