I got the MXM recently, and I've been coming across an issue where my vortech and vectra pumps are appearing as missing on Apex. Sometimes it's just one device, and today all my devices are missing. I have to unplug the aquabus for the MXM and plug it back in for the devices to get deteched again. This has been happening a couple times a week. My apex and mobius devices are all in the same controller board, so distance shouldn't be the issue. My wifi router is just across the living room, no more than 6 ft away.
