A:Answer The older MX Anywhere mice you've purchased came with a Unifying receiver, while the MX Anywhere 3S uses the newer Logi Bolt receiver. Unfortunately, these two types of receivers are not intercompatible.
The MX Anywhere 3S is designed to work with Bluetooth, so you can use it wirelessly without a receiver. However, if you'd prefer to use a receiver, you'll need to purchase a separate Logi Bolt receiver, as that's the type that's compatible with this model.
