Short description of error
When I edit Bezier curves and animate them via AnimAll (change Handles to go from "curvy" to "edgy") Blender does not adjust curve according to handle positions (Curve stays "edgy" all the time).
After I touch a handle (move it slightly) the curve is correctly animated.
I am quite new to blender (Only ~1 year experience) and mostly used it for video editing until now, so It might also be a user-error as this is my first Animation. However in this case I would be really happy If you push my understanding in the right direction on how to animate curves/text correctly.
Exact steps for others to reproduce the error
See attached Image-Sequence for detailed problem description.

This is just not supported in the Addon.
It would be a simple addition, just wondering if we should clutter with this Handle Type fcurves by default (might potentionally add a lot of keyframes which many users would not rely on) of if this should be an option?

Bezier curve handles animated correctly, but curve is not adjusted accordingly when animated via AnimAllto AnimAll does not keyframe bezier curve handle typeOk, thanks. I understand now that HandleType is a separate property of curve points.
As a Workaround and maybe permanent solution for my current project I switched to Grease-Pencil animation which supports animating pseudeo Bezier Curves and also gives more precise Keyframe interpolation, which was sufficient.
However real Bezier-Curve animation (maybe also via Grease-Pencil) would be a nice feature for the future.
Hello @Rainer, @lichtwerk is totally right on this, the add-on can be modified to account for this property.
As you said, I reckon it would clutter the animation data if we key this by default, so in my opinion it would be better as an option, along the lines of:
I’ll commit it on the week-end if I find the time. Meanwhile, you can test the change by installing this version if you can’t apply the patch.

This is actually a bug in Blender 3.0+
Reported and will probably roll back the animate handle types option since that would introduce undesired jumps when animating!
