Quoted from Reznnate:While that could be it, unfortunately I doubt it.
I recently unboxed game #135 and haven't played a proper game on it yet because I'm still working through issues.
But my playfield won't go in easily either... I have to push very hard to get it down. Nothing is bent, it's just REALLY tight.
Make sure the wire loom that is on the left
Is not hitting play field. I moved mine more towards the center And was a lot better.
