Hi

I originally installed this switch quite some time ago (maybe 18 months or so?), and although it wouldn't fit the back box properly, the long screws held it well enough to be stable, and the switch worked just fine.

Last week, I finally had the opportunity to change the back box for a deeper one. The switch finally fits. Everything is neat and tidy.

Except... Now the physical switch doesn't trigger properly. If I press hard, directly over the inner button, it will work, but not if pressed normally. The smart functionality also works perfectly - it's definitely a physical issue.

I have tried a few different front plates on it, and tried wedging something behind, but this hasn't helped.

Has anyone else found this issue? Is there an easy fix for it?

Thanks in advance for any suggestions.
