Widget fixes and improvements. • Simplified appearance settings with a live widget preview and clearer colour selection. Playback status checks now recover from a transient connection failure without repeating commands. • Fixed the large Favourites widget’s tap area so artwork and titles both start the selected favourite. • Kept artwork sizes consistent and truncated long titles. • Added a Pure black widgets option in Settings > Appearance, separate from app appearance. • Improved first-command recovery after idle and allowed fresh attempts from widgets showing an old offline status. • Improved playback confirmation while speakers are buffering, with clearer feedback while commands are waiting. • Improved Sonos favourite highlighting across status refreshes, without marking unverified items as playing. • Clarified Live Tile controls and improved command diagnostics. Existing Premium purchases and widget speaker choices are preserved. Favourite highlights use the speaker’s last confirmed state; external changes may not appear immediately.
