Constantly loses workouts – StrongLifts Weight Lifting Log Review

This app continually and consistently loses the data I enter into it. I tried speaking with their support and was finally told I was simply wrong, that I just hadn't entered any. This came as a surprise to me because I'd been diligently entering workouts in it from August 2017-March 2018 before it started dumping them. Which, let me be clear, it does every time now. I still use it for the timing and warmup calculations, but as a workout tracker it's become worthless. That's a shame because then interface is simple and intuitive.
