App needs to be fixed for lock screen malfunction!!!!! – Interval Run Review

I loved this app until something happened when the lock screen was engaged and I'm running and running and thinking, "man it should have told me to walk by now!" And I open my phone to find the app just didn't tell me anything when it was locked and I had gone way longer than I had set it. FIX THIS!!!!!!!!!! Other people have reviewed this problem!!!!!!! Please do something about it - I've had this app for over 5 years. Not cool.
