I also had this issue. I was messing with the ah in the parameter settings. It is interesting that we changed the same parameter and we got the red flag in the same area . I doubt I typed "0" now the app is working normal.OHHHHHH I COULD KISS YOU!
Been trying to fix this for 2 weeks! Bingo!
I tried with a iphone 6 and the app runs better but you cant edit values like the xiaoxiang android app.
Thanks for the tip NwO2kmouse!
