According to the Salesforce Platform Licence Details page:
Lightning Platform licences require a Service Cloud Licence to access Cases:
However I am unable to assign the Service Cloud Licence to the Platform licence Users - the checkbox is greyed out (we have available Service Cloud licences in our org):
Documentation: https://help.salesforce.com/articleView?id=console2_assign_service_feature_license.htm&type=5
As it stands currently, out Platform licence Users cannot access Cases at all, which is sub-optimal - even having read only access would be great when talking to a Customer about a booking if they can see any open or historical Cases this customer has they are better informed to proceed with making a booking etc.
It seems to me that the Platform Licence details page mis-represents the actual access of the Platform licence - which is hard to believe but I can't see any other way to read it!
Any advice and opinions gratefully received.
