(I did research but really struggling right now as I've tried different solutions and no luck + I'm a noob)
I purchased this screen and buttons for my Raspberry pi zero 2 w:

The problem I have is that the screen is always white. I sometimes have to jiggle it a little to get it to turn on, I have to use headers as they aren't soldered to the board.
I know the documention is a tad outdated because their demo script is in python2. But the demo for both c and python just show a white screen.
I have tried many different OS' of different versions of PiOS, including a 2019 version of raspian (which doesn't even boot on the zero 2 w, it just displays the rainbow screen and does nothing).
All I want to do is get the demo working so I can at very least try the rest of the documentation and get the desktop showing on the mini display.
I contacted waveshares support who told me to use bullseye version of raspbian, I did just that and I got the same result, they also copy and pasted some bits of the guide ok the wiki including instructions on how to I stall python 2, despite me telling them the board and using after they asked me.
Any advice?
