Tried to remove my quickfit strap yesterday, impossible to remove one of the two. After pressing much harder on the button, I finally got it off. But I can't put it back on, as one of the sides is not pushing in enough. I suspect some dust / dirt got inside the mechanism. Is there any way to clean this ? I see two screws on the connector, I could try to disassemble it, but I don't think it will be enough to fix this issue. Any idea ? Thanks :)
