small gap in the left crankset

Hi everyone,

I received the tacx neo bike smart 2 weeks and been having the following issue. On every pedal stroke, there is a feeling on the left side as if there was a little gap coming from the crankarm and it was very slightly moving. It is happening on every rotation and that's the only thing I can think about (drives me crazy). It happens less if I am being really careful with my pedaling technique and making really nice circles...

I made a video that shows that the left crankarm is moving slightly from approx 135 to 235 degrees (check for the sound when moving the arm left/right)

I did check the screw already and it is tight.

Anyone experienced this issue?

I bought the bike from Tredz, and waiting for TNT to pick up the parcel for warranty/exchange/refund but wanted to check in here in the meantime if there is an easy fix...

Thank you!

Benjamin
