Original ruling: "it can't take reactions until the end of your next turn.

New ruling: " Open Hand Technique now has the Addle option
to prevent creatures from making Opportunity
Attacks and no longer requires a saving throw.

The saving throw is referring to Playtest 6's Addle, not the current PBH. 

As MPA stated, you're missing the previous playtest monk, whose Addle worked differently from 2014 and from the final playtest one. 

i see thank you so much for the update
