I received my SD OLED 4 days after it went on sale 20th I had seen Gamers Nexus’s video but was unable to find a guide on how to disconnect the ribbon cable so I had to sit there and play with the connector on my left hand side (right side of the device were in a normal position) until I figured out the white latch disconnected the cable. As for the little black cable taped down I just used a small spudger to disconnect the tape.
Having now heard iFixit talk about it I guess they moved the ribbon cable to make it easier to replace and because when removing and reinstalling the motherboard that ribbon cable would often get pinched or ripped.
Personally I do agree the SSD swap was much more tedious this time between the tighter shell fit and not being able to quickly remove the shield. However it’s off set by the good like now if you need to replace that ribbon cable it’s right there and the backplate screws thread into metal fittings making them less likely to strip. Actually funnily enough the backplate which I do agree is much better fit this time I was able to remove by wedging my nails in one side and pulling up.
Curiosity which Deck did you get the LE?
