That is exactly how I felt, could never get it to feel right, suspect a pro pedal shock would have helped.
I tried everything, shock, at pretty much every pressure under the sun, long stem, short stem, flat bars, flat bars with bar ends, risers, wide flats, saddle further back and further forward, bigger tyre on the front to the rear, both the same and vica versa . Nothing worked, it was always a disappointment. Never really hated a bike before but did really hate this one.
Eventually sold it to one very happy customer, wasn’t the bike for me, just to stress this fact as it clearly is a bike loved by many, and clearly not a bad bike at all, just a bad bike for me despite it being perfect on paper.
One thing, what gears are you running? As one thing I did notice was that it did seem to ride better with 3×9 than 1×9. The issues were still there but were strangely less so, seemed to ride best in the big ring, and not sure it liked the 33 tooth ring I used. But this might have been in my head as the suspension design ‘shouldn’t’ be that effected by an increase of one tooth!
Not that helpful advice I know, sorry. I would say a fitting a RP23 shock or similar, is what I would have done if I wanted to keep it, sadly I had got so fed up with it by that stage, that I was very happy to see the back of it.
