What happened?

Updated instance to 1.10 after release.
Created a new PoS for demo purposes, played around with form builder, added newly created form to the PoS (shop + cart layout)
Once demo how the invoice screen now works with the form, the redirect after the form to the invoice is blank (similar to RC1/3 bugs). The return URL ends like ; apps/39HKZ7eZpSYF8f9BpqwpXGN4cd46/pos

Test instance @petzsch is still available or update instance to see.
