App no longer correctly picks up my voice, don’t know why – Vanido: Learn to sing Review

I have used this app for a while as a warm-up before I do any kind of real singing and could always get three stars on the practice, meaning I was singing in the right pitch and everything. Now when it inputs my voice it jumps from high to low in a wavy line and stays constantly either too flat or too sharp, even when I tested against a piano that my voice was right. Previous to this I had taken a break from the app and chalked it up to that but now I think an update has changed the way the app works and broken it. That is such a shame because it used to be a great app.
