The result screen in learning page stays blank and flashes when typing anything in the code editor port.
Hi @safi.ar !
Welcome to the forum!
I edited your post to include the challenge link so we have some context.
On my end, I am able to see the animated penguin and pass the test.
I am not able to replicate your issue.
Can you try this on a different browser without extensions?
I just tested it on my end with google chrome and no extensions.
