It's sandbox preview time again! If you want to get early access to Summer '20 features in your sandbox, follow these instructions.

A little about preview sandboxes

Sandbox instances are split up into two groups — preview and non-preview. Preview instances will be upgraded to the newer version of Salesforce before production instances (e.g. NA2, EU1, AP0) and non-preview instances are upgraded towards the end of a major release along with the majority of production instances.

For the Summer ‘20 Release, the preview instances will be upgraded to Summer ‘20 on May 29 and May 30, 2020, and non-preview instances will be upgraded to Summer ‘20 on July 17 and July 18, 2020.
