What does Using “MX Anywhere 2S” may affect Wi-Fi and Bluetooth connectivity mean in iPadOS? On iPadOS 13.4, the Bluetooth mouse functionality is substantially improved. I have an Logitech MX anywhere that I purchased to test this, and I notice a warning that it may affect WiFi or Bluetooth.


  Using “MX Anywhere 2S” may affect Wi-Fi and Bluetooth connectivity




I know that any Bluetooth device uses 2.4 GHz unmanaged spectrum, so interference is always possible, but I wonder if there’s something specific at issue here or if Apple has documented which mouse devices will not get this warning.

Is there an official explanation why this alert is present or a list of supported protocols, devices, driver upgrades to have the best WiFi and Bluetooth experience on iPads with Bluetooth mice connected?
Some mice, like the MX Anywhere, support both Bluetooth and wireless radio connectivity (this is the connection method where you usually have to use a small USB receiver). This wireless radio uses 2.4 GHz spectrum as well and may interfere with BT and/or 2.4 GHz Wi-Fi.
