Issue with DNS record creation for Apex

Hello,

I am trying to map the apex of my domain name (divebase.cloud) to my Rails app. Your system is requesting me to create a CNAME to alias @, but... that's actually wrong. A CNAME record cannot map to an apex.

I used the ALIAS record from DNSimple, but your system is not recognizing it.

TL;DR I am stuck, I can't map my apex to the app because your system is providing an in correct guidance, and won't recognize the ALIAS record.

Any guidance?

Thanks,

-- Simone

Generally, direct CNAME records at the root or apex level are incompatible with DNS standards (which assert that you should use an "A" or "AAAA" record). However, given the dynamic nature of the modern web and PaaS providers like Railway, some DNS providers have incorporated workarounds enabling CNAME-like records to be associated with root domains.

DNSimple ALIAS - Set up a dynamic ALIAS in DNSimple for your root domain.

I explicitly mentioned I am already using the ALIAS, yet Railway system is not recognizing it. So the issue seems to be on Railway side.
