I'm trying to use the browser-based MATLAB Online to work on a script. However, the Current Folder doesn't show any files in it.

The file does appear in my MATLAB Drive, but there's no way to re-open it in MATLAB Online.

Is there some other step I need to take to get my files to show up? The "Select a new folder" button doesn't show anything either. I'm using Google Chrome and haven't tried any other browsers yet.
I can access the file through the MATLAB Mobile app on iOS, but I want to access it in a web browser.
EDIT: I can now see my files. Here's everything I did since posting this question:
Logged in to MATLAB on iOS, accepted the prompt to log out of my browser session
Opened the file on my phone
Logged back in to MATLAB Online in a browser, accepted prompt to log out of mobile session
Files appeared
It seems likely that I just needed to log out then log back in- I had closed the tab before, but that must not have ended my session.

I encountered the same problem but then I tried to move the file from a folder on my notebook to the 'current folder' in Matlab online by the mouse, and it worked.

I notice that the filename HelloWorld.m has an asterisk beside it. The asterisk indicates that the file has been modified since it was opened or last saved. The modified version has not been saved to disk. So possibly the file simply has not been written to disk yet.

It is my understanding that you are trying to access some files from your desktop.
You could probably upload the files to drive.matlab.com and then Click on 'Browse files'. Choose the file you need to work on.
Hope this helps.
