Really needs to be fixed

I have may problems with this app but I will only list some of them that most concern ms.
First, I do not think the piano needs forte and piano depending on how light you touch. Because when I press hard it messes me up. Or at least have a switch to turn it off. BECAUSE THE ADS ARE BLASTING LOUD! Next, I absolutely HATE the things that say "Slow down" or "Too many fingers" because I DO NOT NEED A REMINDER I KNOW I MESSED UP so please freaking please make a switch or just GET RID OF IT!!!!! Last one I am going to say, when I am playing, it decides to stop right in the middle and glitch. So I press the pause wait a few seconds and then resume the song. I can play 3-4 notes and then it will glitch and lag again and it is SUPER ANNOYING!!! This app makes me SOO MAD!!!
