Anyone else having serious problems getting their custom domains cleared and published? Since the new CNAME setup is needed, I’m waiting hours (and days) while my DNS settings are set in the right way. Is this an issue related to Cloudflare? Not being able to get sites published while old sites from clients are down is very frustrating. Can’t imagine I’m the only one. Before the new servers this was never an issue.
Remove all old A/AAAA records, keep only the required www CNAME, and set Cloud flare to DNS, only, the proxy slows or blocks validation. Same issue popped up on a client site right after the new setup launched.
Thanks Moid for the response 
Meanwhile (that is, it took me a day and the help of WF support) the problem was the TXT with the verification. The name of the record wasn’t set to ‘_webflow’. Instead this was added to the content field with the actual one time verification code… The instruction to the webmaster for the DNS change wasn’t instructive enough. My bad!
