Is this error new in iOS 13.4.1?I just updated iOS and saw this error for the first time.It seems to happen when iOS has been paired with the peripheral, but the peripheral does not currenly have the correct (or any) pairing data. And, for me too, the solution is to Forget it in Settings/Bluetooth and re-pair.Before I updated iOS, the iPad would just fail to communicate in this state, with no apparent error.There are other posts online where the friendly [!] error text was apparently "Unlikely error".I wonder if it is technically possible for the central to ignore the issue and re-pair with the peripheral, but iOS chooses not to because the peripheral may not have the pairing data because it's an impostor.
