Important Announcement: The Winter ‘20 “Turn on Lightning Experience” critical update has been delayed. It will now be activated in your org within 72 hours of January 7, 2020.
Why is the Critical Update being delayed?
As part of our release process, we conduct rigorous testing and build in multiple checkpoints to ensure quality. We’ve discovered a potential technical issue that, while unrelated to Lightning Experience, could impact your general experience with the Winter ‘20 release. To prioritize customer success, we’re applying an abundance of caution and delaying some post-release activities, including activation of the Lightning Experience critical update. The critical update delay applies to orgs that received Winter '20 on October 5 and those that get the new release on October 11.
Can customers turn Lightning Experience on themselves before January 7?
Yes! You can self-enable Lightning Experience before January and we encourage you to do so to take advantage of everything the new interface has to offer. If you’ve been preparing your org and users for the critical update, be confident that the critical update’s delay isn’t related to Lightning Experience and you’re safe to enable the new interface now.
We provide a number of tools that automate and speed up the transition process, including the Lightning Experience Transition Assistant (https://sfdc.co/hD17J). You can also use this group to get answers from Lightning Experience experts.
Where can I get more information?

We apologize for any inconvenience you may experience as a result of this delay.
