I have attempted the first lab in the M103 course “Lab: Launching Mongod” and got it incorrect so I went back to earlier in the course and returned to the Lab. On the lab page it displays “Incorrect! Try again.” while the Interactive Environment is loading then displays “You may be signed into another exercise in a different tab or window. Please close any additional open exercises and refresh this one” even though there are no other tabs of another exercise open. However, if I open the Lab in incognito mode on my computer it works. Could someone advise me on how to fix this issue?
