Problem with motion path

I have a motion path applied to a shape in a fluid box (which is set to static).  The project is teaching kids how to read a foreign language (Hebrew with a different alphabet).  My goal with the motion path is to create a pointer that shows the student to read from right to left.  Everything looks fine when I preview it.  However, when I publish the project and view it in my LMS (Schoology) the motion path is either in a different place or does not stop at the point defined by the project.  To complicate matters, if I view the project through the LMS mobile app on an iPad it is actually fine.  So if I adjust the path in Captivate to accommodate the desktop browser, then it will be off on the iPad and vice versa.  Right now I have it set in between so that it is just a little off on both.
