Edge 520 Plus won't pair after adding a Garmin Instinct Solar watch. When I try to re-pair it, I get this popup screen that says "select an accessory", which is blank and provides no other info. Now what?

Please reach out to our Fitness Cycling Edge Product Support team. I was unable to find any other report.
It will be best you call us and speak with product support on the phone given the unique nature of your issue so steps that will be tried can be performed in real time together. If an option, please call us on another phone that is not your smartphone you are having the issue on within the Connect Mobile APP.
If you are unable to call us over the phone due to your schedule - please feel free to highlight my name and send me a private message. I will be happy to assist you further through email.
