rotating an arrow round an elliptical path is challenging!

Question

Hi all, I have been banging my head against the wall on this for hours. Client wants an arrow to track round a running track-like ellipse, but as the arrow needs to rotate when tracking around the bends one cannot use a single arrow and motion Path as Indesign doesn't have an Auto Orient setting like After Effects. So I created 4 x sequential animations of the arrow with the bends and straights as separate motion paths and setting the arrow to rotate 180 degrees on the 2 x bends. Thought I was ever so smart getting around this and was pleased as punch when my swf preview confirmed that this should work. But... on export and viewing in a browser, the arrowhead goes all wonky around the bend and only rotates at the very end, as well as jumping off the path momentarily. Any ideas on a solution fellow in5 Pros? Here is a hosted export which shows the issue as well as a screen recording of the same file but working in swf preview. I have also packaged up the Indd file if you want to take a look at how I have set it up.
I am working on a Mac Pro, Mojave OS in the latest version on Indd 2019 as I am a cloud member.

Any assistance massively appreciated
Thanks all!

Hi Evan,

Sorry for the delayed answer. Orienting to path is a manual process at this point and difficult to accomplish. I'm working on making a feature that will do this for you in a future version.

For now, it's probably easiest to make the animation in Adobe Animation, export to OAM, then place in InDesign.
