Can't animate with Sprite Resolver and Animator

Hello,
When I try to animate using Animator and Sprite Resolver/Sprite Library, it doesn’t work.
I already went through all the topics on the same matters, and I can’t find any solution.

Here is a video of the exact process I went through and the resulting problem, I can’t see any difference with the sample, yet it doesn’t behave the same way. (The sample objects works fine).
The animation doesn’t work in playmode either.

What am I doing wrong ?
Thanks for your time.

Hello, thanks for reporting this to us. We will take a look to verify if this is a valid bug
You can track the status of the issue at Unity Issue Tracker - [2D][Animation] User-created animation using Sprite Key hash does not update
(If you do not see the page, do wait 1-2 hours for it to update)

Hello, after investigation from our developers this is as expected.
When animating the Sprite Key from changing the Category or Label, do ensure that the keyframe’s tangent in the Animation window is set to Constant, else it would not be able to resolve properly

More info here: Frame-by-frame animation | 2D Animation | 7.0.13

Unfortunately from your video we cannot tell if that’s the case, do let us know if that does not resolve the issue.
