Yes, if you disconnect DudaMobile and remove the DNS pointing to it, it will bring up your desktop site on mobile. It is recommended to have a mobile version of your site, but I understand if you don't want to use Duda anymore. Have you heard about our newest builder that has a mobile editor?
Yes, I have sites using the new builder with the mobile editor built in, I love it. If it wouldn't take forever to rebuild my old site on the new builder, I would. But yes, my dudamobile site is very bad and I can't get it right no matter how much time I spend trying. So do I "delete" the dudamobile site? What do you mean "disconnect" it and remove the DNS pointing to it?
