IPhones work on WiFi but cannot resolve IP using ATT data network.
Does anybody had issues with iPhone and ATT using CNAME. We delegate wip.company.com to GTM and use CNAME for a website. It works with Android, Windows, Linux, etc., IPhones and Ipads work on WiFi but cannot resolve IP using ATT data network. Android on ATT works without issues. Is it Apple bug or I missed something in GTM settings? See dig example bellow dig www.company.com www.company.com. 3600 IN CNAME www.wip.company.com. www.wip.company.com. 300 IN A 200.200.200.200
