PowerBI App (iOS) authenticate with certificate on ADFS

I have succesfully configured OAuth for Power BI Report Server with this document:

https://docs.microsoft.com/en-us/power-bi/consumer/mobile/mobile-oauth-ssrs

And I can authenticate in PowerBI App with login and password. But when i try to select auth with certificate ADFS gives error:

No valid client certificate found in the request. No valid certificates found in the user's certificate store. Please try again after closing and reopening the browser and choosing a different authentication method.

But I can login on with my Safari browser (for example to https://portal.office.com) using certificate. Is there anything I should do on ADFS/WAP? Or PowerBI App just cant use certificates installed with Intune?
