I recently upgraded my EISY to v6.0 and the update seemed to go smoothly, however since updating I keep getting communication error messages. Sometimes the devices will work fine and then other times I receive error message cannot communicate with that same device. There are times when the UD Mobile app seems extremely slow to respond as well. I have tried several times to revert back to the 5.8 backup I completed just before upgrading to v6.0 but this has not worked. Also I have tested/reset/restored my PLM and this has not seemed to work consistently. Any advice on how to revert back to 5.9 (I'm not even sure this is possible) OR assistance with addressing communication errors would be great!
