Boring lengthy math assignments (like 30 identical math problems to unlock the castle but then the castle isn't unlocked), some cartoons on repeat which prevented us to move on the next task. Too many US currency questions, we are in Vietnam and don't care about the US currency system. Books are ok but then again tons of questions and motivational talks afterwards. Not only my kid is bored but me as well. Sciences section doesn't even work or it's not really user-friendly because we tried 3 times and still didn't figure out how to collect 7 tokens. In general, very boring content and annoying app logistics.
