Why does MATLAB Online behave so slowly, and even get stuck on the loading page?

I have been using MATLAB Online for several days to work on a project remotely. The most recent time I ran my code, I forgot to suppress the output of a loop that cycles through a cell array, causing a large amount of text to try to display in the MATLAB Command Window. I used ctrl+c to kill the program, but the webpage became unresponsive.

Now, when I try to load MATLAB Online, I get a message that I have a session active, which asks me to log out of that session and start a new one. The page then gets stuck at its initial loading animation. I have let the page attempt to load for over an hour, with no change. I have also tried clearing my cookies and using a different browser.

Related to this, MATLAB Online behaves very slowly, even when typing in the MATLAB Command Window.

Your MATLAB Online session data has become corrupted. This happens to be the cause for slow behavior and MATLAB hanging while loading.

Follow the steps below to resolve the issue:

1. Go to

MATLAB Drive

2. Log in

3. In upper right, click on your name and select “Show Hidden Files”

4. Delete all content inside the ".session" folder

5. Go to MATLAB Online

6. Log in

Is Matlab online offline? I can only see the loading bar for an hour now. Already deleted the .session folder and tried different computers and browsers...
