Very spotty performance with Ford Sync

[aszure]

This has been brought up in the past, but there have been many updates since those last posts. My ford sync is syncing with spotify maybe 30% of the time. I can't find a rhyme nor reason why it is doing this. I've tried all the usual phone stuff (reboot, reinstall app, etc) and same thing. Works ok over BT, no issues there. Just can't says it can't find spotify, which is clearly running. I will probably pull the fuse tonight, and reset the system and see if that helps, but that's a really poor way to resolve this issue. Any thoughts?
