I received my new blue star ez app set... set it up... downloaded app, uploaded firmware... when I go to throttle up... I hear the locomotive internals trying to do "something"... I put a different HO loco on the track and def getting power... same when plugging a DC pack into the track.  But; this locomotive wont move..

UPDATE:  I sort of "gently moved the wheels to see if something was stuck" and... out of nowhere- the train is moving on the track as it should...  Do you recommend I return this to walmart for a replacement?
