In the past, the "notify direct" flag controlled all network syncing, propagating all color changes to other devices on the network. Pressing the UI Sync button only toggled this flag, so "notify direct" was set to false by default.
In version 0.15, a separate "master" sync flag was introduced, and the UI Sync button now only activates this master flag. However, the rest of the flag defaults weren't configured to sync anything at all. As a result, users pressing Sync saw *no* syncing at all, leading to multiple bug reports.
Defaults are now user-friendly: Enabling Sync on a WLED device syncs all of *its* color changes, whether made via the UI, API or remote button, providing a consistent experience which matches the intended behavior from past WLED versions.
Philips Hue sync is now also disabled by default, making the stock defaults focused on WLED devices. Users with other RGB ecosystems can manually enable the Hue or Alexa syncing in the settings.
