Panels and signage now recover on their own after a failed load, Google Calendar rooms keep syncing, and check-in leaves a meeting's time zone alone.

What changed

Fixes

  • Room panels and signage screens could stay blank after part of the app failed to load.
  • A room panel or signage screen could fail to sign in after waking up or reconnecting.
  • A Google Calendar room stopped syncing after a repeating meeting was changed with This and following events.
  • Checking in, checking out or extending a meeting could change its time zone, and on a Google Calendar or Microsoft 365 room the change reached the organizer's calendar.
