Pivots in ANIMATE are a little more complicated than they are in FLASH. In Flash, when you edit a Symbol pivot in order to reset a rotation/scale point, you enter the Symbol, select the pivot and drag it into place, and that's pretty much all there is to it.
It took a lot of trial and error (and I had to re-do a lot of messed up animation) for me to realize that there are "Pivot settings" in ANIMATE to pay attention to. Not only this, there are Drawing Pivots, Symbol Pivots and Peg Pivots and with Symbol Pivots, there are two levels of editing involved.
1. To reset the Symbol Pivot (for rotation/scaling) when you drag a Symbol's pivot to a new position in the Camera View, this is only a temporary change that applies to that one action. The pivot doesn't actually change position. It's still there.To set a new permanent Symbol pivot, click on the Pivot Tool in the left-side toolbar first, before dragging that pivot. All instances will now have the new pivot position. *This is done on the top level, not inside the Symbol.
2. You can also reset the Drawing Pivots inside the Symbol. These pivots are not linked to the Symbol Pivot unless if you Copy Pivot to Parent Symbol
after editing each pivot. Note that your Drawing Pivot and Symbol Pivot will now be the same, and I find it less confusing to work this way especially when I need to add new drawings to my Symbol.

When editing pivots inside the Symbol, note the
Set Pivot For All Frames option. If this is enabled, your new pivot will apply to the entire layer of drawings inside the Symbol. If you disable this first, each drawing can have its own pivot position. This is important when the drawings (eg, hands or legs) inside a Symbol are positioned all over the place and they don't share the same pivot position.
And then using the Library Drawing Substitution Feature, when I swap between different drawings, even though they are not drawn registered together, when I am in the Top Level/Camera View, they will appear registered in the right place.
A little word of warning: If a Symbol's pivot point is reset, all CHILD SYMBOLS attached to this Symbol will also be affected.
I hope this makes sense...
