Otter rep came into my T-Mobile store telling me I should try the app and that it’s easy to use, fast and efficient way of training. It is none of these, problems from starting videos, to trouble to doing surveys. I’m unable to do a survey for an activity because the drop down menu doesn’t work, and THERES 5 DROP DOWNS that need to be filled out. Wasted 20 minutes of my life trying to get the app to work, so I deleted it. Never downloading again, waste of my time
