Completion: Learn Bash by Building a Boilerplate - Build a Boilerplate

I completed the exercise: Build a Boilerplate twice in CodeSpaces, however it is not verified in freeCodeCamp. I refreshed the website many times, and still don’t get an update in freeCodeCamp.

Why isn’t there an update in the website to say that I have finished the boilerplate section?

If you clicked the last button presented in the tutorial and the tutorial had your user token in it as per the given instructions, it should sync with the fcc servers and update them that you have completed the workshop.
If you cannot see that in the fcc side, even after waiting some time after then refreshing the page, I would simply move on. The check mark has no effect on your ability to continue anyway.
