I have been trying to follow the Hello Nextflow tutorial, with the first step being to open a github codespace to run the material in. The tutorial says it can take a little time to get started, but I have been waiting for four hours now. Presumably it shouldn’t take this long?

Hey, sorry I just saw this. It should only take a few minutes. If it takes longer, try refreshing the page or start again with codespace creation. Let me know if that doesn’t work.

I had refreshed yesterday, but that did not help. I started again and the creation seems to be working. THanks
