Can I unequip a streak freeze?
OK, so I just decided to purchase a streak freeze, just in case I forget to practice sometime. However, I then realized I'm going on a trip for several days, and it's very likely I'll have to forgo Duolingo for more than one day. If I'm right, this means my streak freeze will be a waste. If I know I don't want it now, is there a way I can sort of return it, or at least unequip it?
EDIT: I will have access to a computer, so the problem is now gone. I still would like to see this feature added, though. But what the heck, this site is practically making me fluent in Italian, so I can't complain if little things like this don't get done.
