Did you flash Gapps with the ROM?
Did you flash using TWRP 3.0.0.2?
Were your Gapps:
Open Gapps Arm 6 Mini?

I've installed gApps after flashing the rom, but without rebooting. on 1st attempt, I haven't installed gapps.
I'm using : open_gapps-arm-6.0-mini-20160313
I was using ClockWordRecovery as my TeamWinRecovery was stuck (flashing on splash screen).
