Why only IP Addresses and no Domain names custom Server connection?

ios

#1

I'm a Plex user for a really long time and I don't get it why I can't put Domain names in the custom Server connection on the iOS App. This makes absolutely no sense from the technical view - how am I supposed to reach my Server with a Dynamic DNS Record? The IP Changes every 24 Hours, and I do not want to use Plex Pass.

Okay, i got it working with the remote access, but anyways, should be allowed to connect to Domains too!
