Is there anyone out there right now still struggling with either Tapatalk or Mobile? I made some DNS changes last night and everything should have propagated out. You might see some issues with corporate filters for a little while because Nutopia was technically an unknown/new domain for a little while last night.
Additionally, while the DNS issue was occurring I had to direct Tapatalk to http://nutopiasports.com rather than the WWW. You need to remove your saved instance of Nutopia in tapatalk and then re-add it.
