Right rail issue after replacement


I recently purchased a broken switch on eBay which had a broken right joy-con rail. I bought a replacement part from iFixit and replaced it, and still am having issues. I’d be happy to provide pictures if needed. Could anyone think of something I did wrong?

In that case the rail itself seems not to be the problem. Pictures are always helpful - maybe the connector itself is faulty but could also be some other problems .

@taugust camera was really shaky, but let me know if you would like a closer look at something else. Thanks again!
