Device Trust issues after v11 upgrade

There is one more piece to the trust that you may or may have not completed. I've had v11 pairs where it was required and where it wasn't. I had to export the device certificate from each device and import them on the other device in the pair. You have to go to System>Device Certificates>Trusted Device Certificates and import the certificate from the other device in the pair. I think best practice is to do this before building any other part of the device trust so you probably should completely disassemble your device trust before doing this. I don't think it would hurt if you didn't though....

Sorry to waste your time if you've already done this.
