When I try to study my grammar schedule, I get this message: The quiz cannot load with your current settings. Please check your quiz question options and make sure you have a few quiz modes selected. There are no quiz modes to select, though, and I can't see anything in the settings that would limit what terms I study...
I have this issue as well. I've tried adjusting the settings, in particular I saw that there were some terms that I studied yesterday that were listed as "cannot be studied" that I manually adjusted the mastery level for to take them off that list. I don't know why they were on that list though, I haven't used the options to block terms at all.
