stupid question

[casi]

I swore I would never buy gems, but I broke down and did it. I purchased a bunch of mix and match challenges.   Now for the stupid question.  Can I activate more than one of them at a time?  I am working on a time consuming one and want a break.  I just don't want to lose the progress I have made so far.

Unfortunately, you can only do one at a time.
