Great app but could be better

Great app. Please make distinction of inland/international more apparent. Also, when completing every rule please allow for resetting the progress so that I can go back and “learn.” After I finished everything there was a window congratulating me on getting through everything but when I attempted to reset, the app did not allow it. Thank you.

Great for SWOs going to BDOC

Great app
