Hello Martin,
When I visit the URL that you posted according to point 7 it resolves OK!
I think you are running into some cache issues that is very common with SPPB. Please also have in mind that version 4.x in the SPPB has many bugs were you need to create and build work-a-rounds until the code is fixed and polished.
I have done the scenario you have several times but a complete restart and cache clean normally resolves all license issues. I do also know that it was some issues with the Joomshaper license system, if that is resolved or not is outside my control.
