Help needed with wp

real noob question but seriously can't find the setting to do it. Got this message
Ad unit is too small, vi stories is not working on your site.

The minimum vi stories unit size is 336x280px.
Please insert the tag into a bigger unit.

But can't work out how to change the size of ads? Any help would be appreciated

Did you manage to figure it out?

Sadly I have no experience with VI. Perhaps sending them an email will get you some feedback on how to fix the problem: https://www.vi.ai/publisherfaq/

I’m a bit slow when it comes to replying and just reread your comment.

Isn’t it possible to apply some CSS to carve out a big enough space for ads in the header?
