Index S2 doesn't sync more than 1 account

New S2 arrived today. Wife initially set it up on her account, works, syncs in seconds to Garmin Connect. Added myself as a second user, couldn't sync. Reset device, couldn't sync. Connected to a dedicated 2.4Gz network, couldn't sync. Removed device completely from her account, using mine for ownership, still couldn't sync. Added her as a secondary and it syncs with her account. When I step on the scale, my account shows, and then a green checkmark next to the wifi appears.

Anyone have ideas?
