I use a small Wifi access point and POE injector to provide connectivity between my iPad and rack profiler. For venues where problems occur I keep a Lightning-to-ethernet adapter on hand. After updating to the current release version of 10.x the iOS Rig Manager can no longer connect to the profiler when running either wired or wireless. It appears to see the unit and pops up a box with its correct name and a "Connect" button. BUT, the connect button is grayed out and does nothing. This was working just fine before the update so it seems something has broken.
Apple App store does not show any updates available, so I have to assume I'm running the latest manager software.
UPDATE: Just after posting this I tried removing and reinstalling Rig Manager. That brought it right back to life. Hopefully someone else can benefit from my experience.
