I am also confused with all this happening the past several days. On the first daily challenge, I get the error message - for example, yesterday was Paranormal Adventures, today it is Mahjong Safari. But, I am able to do the 2nd daily challenge with no problem. I am not having issues with any of the other challenges either. Not sure how to go about the work around - I am fairly computer literate, but am totally lost by what the previous strands show as a work around. Thanks for any help you can provide!
