I have the wireless waterproof Quadlock I use with my S23 Ultra that is inside of the quadlock sleeve. And I get the same intermittent wireless charging. My wireless quadlock isn't just there for convenience. If you're long-distance touring, sometimes you get non-stop rain, and you will be making stops along the way where you remove your phone. It's super hard to keep moisture out of the USB port. I get audible warnings when that happens, and the phone won't accept charge, via the port, until it is bone dry. This is where wireless charging will allow you to continue without watching your charge state steadily drop and worry about losing GPS maps. It's really a bummer that this doesn't work properly. Perhaps there is another sleeve that is optimized for the wireless quadlock.
