The new M1 based Macs have been out with customers for about a week now and some users are reporting issues with Bluetooth. Issues with some accessories not working all together or some devices being intermittent.
Originally reported by MacRumors who have said that users affected have been sharing the issues on Reddit and the MacRumors forums and that the models affected are the M1 models so the MacBook Air, MacBook Pro 13 and the Mac mini.
The Mac mini does seem to be the one that is most affected, with various glitches and one customer in particular did get a replacement Mac from Apple.
So far, Apple hasn’t said anything about this issue, this could be a small issue or it could be widespread.
