Unable to progress in PHP

Question

I’m unable to progress to the module 6 quiz in PHP. It keeps telling me to complete the previous lesson but they have all been completed and no matter how many times I complete them again it’s still locked. Is this a bug?

Answer 1

I've heard of people having this kind of issue. The solution for them was to clear their cache, app data, and reinstall the app.
I also had this issue but I just hit the unlock button to clear it.

Answer 2

Thanks. I force quit the app and reopened it and it’s working again. I also wasn’t able to see your reply till I did that though I did have a new notification for it.
