Can't continue study

I have finished the Message Mixer exerecise and now I want to continue.
However the ‘Up Next’ button remains unresponsive.
How can I continue?

Many thanks

sorry, my mistake.
just noticed I had not checked all progress checkboxes.
all good now.


Which study you mean??

I also have done this Message Mixer exercise. And I am continuing it for a while. I think there must be an error on your side that you need to check again to continue this exercise. Because as I said this site EssaywritingNetNz smoothly running in my PC and I am now in love with this. After rechecking your error you also join us in it.
