Video recently stopped working on mobile devices - ????

[sdg5]

My video has been working for some weeks. 

Recently I checked my store and it's stopped loading. Just the grey placeholder.

It's only 9.5mb. I've re-encoded it, and re-uploaded. Same result. Broken.

Also I notice that my shopify speed score increased by 5 points on the 15th of Sept from 65 to 70. I haven't changed anything. It's likely been broken for all this time. How disapointing.

Any fixes shopify staff?

I note that when I went to post this I got an error screen - yellow with red text - another symptom of a broken and buggy platform. Yikes.
