v1.11.0-beta.2

Notification Improvements (#2364)
  - Fixed: The change for production didn't full make it into v1.11.0-beta.1 - this change restores the code which removes the old notification when we add a new one
  - Fixed: Notifications could be orphaned in notification center if they were added/removed quickly
  - Fixed: Notifications weren't removed properly when read on a linked device

Dev: Better logging when we receive a read sync from a linked device (#2364)
