I have not find html5 conversion option under Commands > Converts to Others Document format on Animate CC
There is only two dropdown menu- WebGl (Preview) and Flash ActionScript 3.0 / AIR.
Please anyone help me.
The problem is solved, html5 conversion not available when I newly create HTML5 Canvas Page.
Yes, it's the "other" word that explains things. If you make an AS3 FLA, AS3 won't be in that list either.
