I got the purple batch which seemed thinner than other boards I'd seen online. Mine slides without catching the springs.
Here's a link to Modsiah's tutorial:
About 3/4 into the vid he shows how to install if it does catch the spring. Hope this helps.
I have the exact same issue with no results yet. I got 2 boards from Modsiah, and they both get the same formatting request. Perhaps an enso issue? I'd be most grateful for a solution. Love what's been done with the vita thanks to this community!
I took a look at the rail and noticed that the two last pins were soldered for some reason, luckly I still had the rail of my broken joycon so after I swapped them I was able to use it attached to the console
