Hi @Dave
- ,
What is the error message you are seeing on your site?
- Can you look at status.salesforce.com for both of your instances and let us know which patch of Spring '21 each is on?
- Do you know what Spring '21 patch your Sandbox was on when it was working?
-
On our end I’ve verified that this use case works in Spring '21. The use cases I checked were public Force.com Sites on
v2 - Boston (13.0.14) - Spring '21 Patch 8.5
- v1 - Boston (13.0.8) - Spring '21 Patch 8.6
