Hello! Sorry the console is still not loading for you. It was working for me yesterday (for a bit it wasn't, so I'm in this case a good guinea pig), but later yesterday was working and today is also working. Also very few reports of such problems today or later yesterday.
Note any delays I've recently experienced have been at most somewhere between 30 and 60 seconds, and those are for in-challenge Docker-based commands on the cli; if it takes longer than that something different than expected is happening for you, and in other cases, like for the first prompt, the delay is much less, like 2 to 5 seconds.
Please provide some more details:
- url of the challenge, the code you're submitting
- a screenshot of your entire browser when you notice this loading
