Adam Adam, please add this, I have seen this request for more than 3 years and understand that this setting is at the bottom of priority, and there's no sense in asking, but you can make a lot of customers happy with a simple feature.
A lot of hosters that use Enhance provide CF and other CDNs and all their customers always see this message... + they see the preview website instead of the domain link. Cloudflare integration is buggy too, and deletes all records from CF + after every DNS change; it deletes all records and writes all again instead to update only one record.
So, in total, there is still no alternative way to use a DNS provider with CDN to avoid this banner.
I saw that some hosting panels show notification only on the domain configuration tab + if here is CF they say that they just can't check it, and that's all.
Thanks for your hard work.
