Unfixed Bluetooth problems with wireless devices (mouse/keyboard) remain a big reason not to buy this otherwise useful device. For some time, I thought the problem was my devices, but google searches recently revealed that in fact the problems are common. Amazon will not allow the posting of links, but stories dating back to early 2021 are easily found by googling "mac mini" and "chip" and  bluetooth. Some days, four or more failures occur and require a reboot to restore connectivity.
