Kevin, thanks for being one of the one to bring this issue to our attention. You can see the latest update from Skuid in the public announcement Salesforce’s Spring ‘20 Release: Changes regarding guest users starting March 1, 2020.
Highlights
- The Skuid Product Engineering team is working on a product change to restore the ability for Guest Users to use Skuid’s File Upload component to upload attachments to records. This change will be available in 11.2.30 and 12.2.14.
- If your guest users need to access records they have created, this should be handled sharing rules, Apex, or Flows.
- For more details, please see this article on how Salesforce recommends that customers write Apex to work outside of the security model you have configured for your Org.
