Mine doesn’t seem to have much dust in it (I don’t usually keep it in a pocket) and it seems like the cable seats all the way, but more of a situation where the metal housing is bent so doesn’t grip the cable properly. 🤷

Edit: well ill be… I got a needle in there. Very little came out. Cable seats in what looks like the exact same depth as before, but now it holds the cable better. Mind blown. Apparently 0.1mm worth of dirt is all it takes
