That guide was great, I used it to replace my left-click switch, which wasn't working anymore. However, I thought it would be a good idea to also preventively replace the right-click switch at the same time ( I replace the 10M switches with 50M switches as well).

now my left-click is working again (yay!) but my right-click isn't working anymore. does anyone has an idea what I might have done wrong? I'm pretty sure I followed all the steps closely. Might I have damaged somthing while soldering?

I also asked this as a question in the forum (with pictures)
