One reaaaaally annoying bug I’ve used this app for like 6 years on and off now. I redownloaded it again recently and there’s a new bug that caused me to write this review: Whenever I exit the app for maybe longer than a minute (whether it’s to run for a little bit, answer a phone call, etc), and then I return to the app, the deck that I was currently halfway through has disappeared and I’m back at the Home Screen of the app. All my progress is lost and it’s really hard to start a new deck because I don’t remember all the cards I had already completed. This is pretty frustrating when it happens twice during a workout. Otherwise, this app has been one of my favorite workouts for a long time, but this one bug might make me delete it for good : /
