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 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.

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

I have also tried clearing my cookies and using a different browser.

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

To resolve the issue:

1. Go to https://drive.matlab.com

2. Log in

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

4. Delete the .session folder

5. Go to https://matlab.mathworks.com

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...
