Had a refurbished 645M sent to me today but can't download my playlists using Spotify. I've updated software using Express, linked to my home wifi network, successfully checked connectivity on my watch, but when i try to download i get a spinning "searching for wifi networks" message before an error showing "Unable to download certificates" comes up. Any help would be appreciated. My original 645M, returned because of the broken band mounting issue, didn't have this problem.
