Issue with Rhoa mounting and controller

So i have unlocked the rhoa mount standing by me. But no buttons on controller will let me mount it. If i exit and switch to mnk i can mount it with no issue. Anyone found a solution? Or do us roller players need to wait for a hot fix?

Im on MKB and I cnt mount it or find the skill "mount minion"

I had the same problem. Hold select-> Set Bonda and there you got option Mount

how do u make it run fast
