Setup for remote access by the host is more work, ofc. Remote access on users end can be more difficult depending on how the host sets things up.
Most popular freebie approach seems to be tailscale VPN. Which requires remote users to connect through the Tailscale VPN. And for the host the free Tailscale option has a cap of 3 users. There is probably a learning curve and perhaps frustration for a low-comfort-with-tech type person.
Requires some money but I think the easiest remote user experience is Cloud Flare. This is what my brother does, so I haven’t seen it from his end, but on my end it is very easy to access as a user.
Both have so many help guides online, Tailscale or Cloud Flare.
I use Podcast Addict too. Found it well over six years ago and never bothered to look for another.
