Guest Users cannot upload files in Summer '20

Hello together,

guest users cannot upload files anymore with the new Summer '20 release.

Step to reproduce:
1. You will need a sandbox with the Summer '20 release. 
2. Create a flow (any context even the new system mode with no permission restrictions) with the standard File Input component provided by Salesforce.
3. Make this flow available to a Guest User profile.
4. Notice that the Guest users can't upload any files.

Does anyone else noticed this behaviour and has a workaround.

Best regards,
Björn

Hi,

You can create Guest user sharing rules to give read permission in summer 20. It might solve your issue.
