Metropolis Slide function not working?

Hi - I’m not sure if I should query this here or go straight to support @ Intellijel?
I’ve just bought a new Metropolis & everything seems to work fine apart from the slide function.
There seems to be no slide at all & no response from the slide time pot. The slide/skip button LEDs work fine. The gate pot functions & I’m able to swap the bSLId bSKIP functions in CONFIG but there is no pitch slide.
I’ve tried it with several different power sources & oscillators.
It’s on Firmware v1.36
Is it possible that I’ve disabled the slide function by accident in some way?
