And to answer OP question: Sneak Attack is now done as separate damage instance, which btw opens up the way for lots of exploits. So when you see 1d6+3+1d6 on current Sneak Attack button, it deals 1d6+3, and then it deals another 1d6. If something modifies the damage, both damage instances are modified like they are a completely separate attacks. For example, if you have Great Weapon Master enabled, both attacks get +10. See here:

I looked at the hit points of the enemy before and after the attack, so that was not the problem.
Also I don't think you need toggling at all.
There is a separate button for sneak attack and for normal attack.
The sneak attack button should only be enabled when you really can make a sneak attack.
It is that simple. It is rediculous that I can choose that option even though it does not work.
