I have no update and have not had time to open a ticket with Neptune. My probe name is already shortened so that isn't the issue. I have noticed that it does occur every time I initiate a feed mode via Fusion.
All units have had firmware updated, changing plugs doesn't work, and deleting the module doesn't work. I would switch to a tablet as a dedicated display, but I also have regular lag issues (wired and wireless) when making changes (outlet on/off/auto) in fusion so that wouldn't be a great solution either.
