Once I start a campaign, is it possible to edit the domain?

[comerecommended]

I accidentally submitted a subdomain instead of the root domain. Is it possible to fix this? Or how should this be addressed? Thanks in advance!

You'll have to re-create it.

You can delete the current one if you need by going into the campaign > Overview > Campaign settings. Scroll right to the bottom and click delete.
