Great choices of encryptions to learn but I honestly would enjoy this more if there was an option to use and learn the bifid cipher

I really like what's provided on this app, the only problem is when I type in the correct answer it doesn't do anything. I’ve checked my answers with the provided cipher section and they are right, but it doesn't do anything when I type it into the answer bar. Weirdly enough it did tell me I was right for the emoji one, just none of the others. If this gets fixed I will change my review to five stars because it is a great app.
