SOLVED !!
vst3 file hadn't overwritten the previous one.
That was down to me - I 'Nest' my plugin files ...
Some updaters find them, some don't 🙄
I'll leave this up, just in case.
Original post -
Arturia Pigments 3.5 not opening for me in Bitwig OR Studio One
Standalone opens and works fine except it's not picking up the Graphics for my Expansion Banks (not a Major Fault)
Is it just me having this problem ?
