I previously used Iphone 6 on both devices without any issues. It still works on the Iphone 6.
On the Iphone SE with latest upgrades I reinstalled VictronConnect and it keeps on asking for the pairing code (000000) but that is obviously not accepted. However just sometimes my settings in the Iphone show the device is connected yet the App won't connect to either device. But it disappears and is not on the list of paired devices on the phone.
