I tore my tank down to change the sand and one of my xr15 gen 4 pro, won't re add to my account. I've tried everything I can think of. I have factory reset it via Connection Manger and ESL, and updated firmware. When I tried to Add via USB (because it won't add wirelessly), it walked me through the prompts and said that it had been "successfully Imported" only for it not to show on the device list. I can control my MP 40's and the other Radion so I know the Reeflink is working. I purchased both of the lights brand new so I know it's not on another users account. Ecotech is conveniently open while I'm working, so calling them is out at the moment. Hopefully someone can help. Thanks again!
