Forerunner 965 Spotify Sync/Download Issues?

My Garmin won't download my Spotify playlists. It starts the download and then either reaches a ceratin % and never progresses or presents a "Sync Failed" notification.

I have tried all the suggestions I could find. Its charged 100%, on charge, next to my router, deleted and redownloaded Spotify, turned the watch off and on, reset the watch settings and nothing.

It's getting so frustrating!

UPDATE: Fixed by downgrading my wifi router security settings.. so stupid
