Blank Blocks section

Hey, we’re using Thunkable with a group of students and a couple of them are seeing a blank view when going into the “Blocks” view – none of the normal parts are visible, not the left sidebar of components, no code and the zoom/pan controls that are usually on the right side. The students are mostly new users, using pretty current Safari or Chrome browsers.

I don’t see any controls to show/hide parts of the UI, so I assume this is a bug. Is this a known issue? Any tricks to get that section to reload?

Have all of the students use Chrome. I’ve seen something similar in Safari.
