New featureYou can now turn off the answer-streak combo effect
A "Combo effect for answer streaks" switch is now in the learning settings and the in-quiz settings. When off, you'll see the regular correct-answer reaction.
In quizzes, exercises and lessons, you can turn off the color changes, confetti, shaking, sounds and strong vibration that appear on answer streaks. It stays on by default.
Streaks are still counted, so turning it back on picks up where you left off.
