I notice an oddity since the previous beta and continuing to this one. When I select update downloads in the spotify music app it seems to sync up any recent changes I have made to my playlists on the watch, but when the sync is done and I try and backout to get to the main watchface I get stuck on a white screen. The only way I can solve this is to hard reset the watch. I have tried resetting, downgrading, upgrading etc. (all suggested actions when a beta might not work properly) but nothing seems to correct it. Is this a known issue? As a workaround, instead of selecting update downloads I usually just select add music and then re-select the playlist that's already on my watch. This seems to work and syncs properly.
