I am having the same problem as the first user. So far, I have been unable to assign any lesson plans because the app crashes as soon as I tap the date to assign. I notice this problem was mentioned several months ago. Has a solution been found in that time? Has this app been updated to address this serious concern?
I truly want this app to work, and this to be my only planning tool for the next 14 years, but if the bugs are this big with no fixes, I'm starting to worry that I've wasted $20 and a lot of time!
