Hi @BitSmithy ，

If you're publishing your app in Microsoft Store, your app will be signed with a trusted certificate for you.

What type of certificate did you use? Did you get it from a store? Or was it just a temporary certificate?

Thank you.

I dont know, how to check it? I attached my app with Windows Store using VS function: Project > Publish > Attach app with store, so I thing it should have to be right signed (but maybe I am wrong here).

Hi @BitSmithy ，

Could you try selecting a different certificate? There should be a list for you to choose from(After click Project > Publish > Attach app with store).
