Orisa's Halt in Experimental

Queued for experimental tank today (13/02/22). Right-clicking for Orisa’s halt ability set off the cooldown timer on the ability, but the animation never played and the ball was never sent out or activated.

Patch notes say increased duration, nothing about what is being experienced. I played Orisa and the right click button was red until you got close to enemies and when you could click it, only got an animation but no orb, then it went on cool down.
As for Symmetra, I was unaware her orbs healed…? What’s that all about?
