  • Limited offline functionality for non-iCloud calendars

Google Optimize

  • Google Optimize and Optimize 360 were sunset and are no longer available as of September 30, 2023
  • Any experiments and personalizations still running on that date were ended by Google
  • Google directs former users to third-party A/B testing tools, naming AB Tasty, Optimizely and VWO, rather than a replacement Google product
