[Claiming free UI Kit / macro pack doesn't work]

Same situation. What are we supposed to do here?

 

Thank you in advance

[if I buy the windows 10 version do I get the extras such as toon brushes?]

So if I do decide to buy Affinity Designer from the Microsoft Store, I will get access to the Grade UI-Kit, is that correct? Or what do you mean by "claim anyway"?
