Hey! Had the same problem since Monterey. Tried the so often proposed off/on switching, the restart and the emptying the NVRAM, but no result... it kept not scrolling after every single sleep. Same result, after every sleep, the mouse wasn't scrolling anymore. Tried to completely delete the mouse from the Bluetooth devices on the iMac and pairing it again. And since 48h, no "not-scrolling" problem with my Magic Mouse anymore, hope this stays like that. Kind regards
