Information provided by Apple (as of iOS 13.4 and iPadOS 13.4) states that the message is to inform consumers of possible performance issues that could impact the functionality of their device by having too many unused Bluetooth device actively paired at the same time. Their recommendation to reduce the wireless connection impact is to disconnect unused Bluetooth devices that are not actively in use.
This can be done by going into Settings -> Bluetooth, tap the blue information button next to the accessory's name, then tap Disconnect or Forget.
We fully test our devices to ensure proper performance with Apple devices running the latest iOS or iPadOS operating systems to confirm compatibility.
