I am trying to finish the tutorial, but I can't since I can't leave the island through the portal. I tried refreshing and clearing my cache and other stuff like that. I even waited a few days to see if it would work, but it didn't. I tried moving off of the portal and back onto the portal, but that didn't work either. And I did click the portal button every time I was on the portal. I even tried a different browser, but to no avail.

I just checked you tutorial and I don't see any problem right now, the portal just button worked as it should. We had some problems with tutorial islands several days ago but they were solved at the same day when they appeared, and all stucked users were moved to the next stage to avoid confusion.

I moved you to the next tutorial stage.

Sorry for the inconvenience.

Same Problem goes for me tried to leve the island but the portal button didn't work.
