Mastery tokens in nexus blitz

On purpose, as I hear. Nexus Blitz is in, like, public feedback testing right now.

I just got an s+ on riven and she is lvl 5 but i didn't get a token, is this a glitch or on purpose?

Pretty sure tokens are only awarded on the rift. Think when they introduced that, they said that then.

Me too, i get 2 S + on Lux in Nexus Blitz and she îs level 5, and i didn t get a token.

Report it to Riot. See if they can give you the tokens if it is a glitch or not.
