Editor: cannot preview drafts on a WordPress.com site with a custom domain #14220
Description
We received the following report:
I am currently unable to use the View and Preview functions on my Wordpress App on iPad. I receive a 404 page not found error each time. The issue arises when I attempt to preview or view my drafts. Any of the drafts on my site will show the effect.
- Type of site: WordPress.com Premium with a custom domain
- WPiOS 14.8.2
- iPad Pro 9.7-inch (WiFi/Cellular) (iPad6,4)
- iOS 13.4.1
Note: the app logs provided by the user showing an editor session with a preview doesn't seem to indicate a problem (is it possible we aren't logging failed previews in this flow and so app logs won't be helpful in this type of case?):
