We have built a simple solutions using SharePoint lists and the new custom forms with PowerApps in SharePoint.
Our plan was to let guest users access this SharePoint site and also these custom forms (this in order to request new equipment and user management.)
However it seems that custom SharePoint forms are not working for our guest users - and it's not reverting back to the standard form either.
The guest user will just get a big white blank screen when trying to add or edit an item.
We have also tried to add an E1 license to the guest user - then he gets an error message that says: "App is not working, update your web browser or try again later". (tried this with multiple guest users from different tenants)
Are there anything in the roadmap to get this working, or will it simply not be supported?
