It‘s working fine here. Are you on a VPN or have a router firewall?
Hey, thank you for responding.
I tried it without VPN, reinstalled the app, it just won't work. Seems it's not only the issue with audible source, same thing with built in music sources. Really at a loss on what to do.
This really seems like an issue local to your system. Do you have any firewalls, also on your router, or do you access via a mobile connection?
@Florian Do you have any idea of what could be an issue?
I finally got it resolved, of course it was all my fault, for some reason my Little Snitch was blocking the outgoing connections.
Now when I finally have it set up, I've been writing an 'improved' Audible Tag Source, I will probably share it as well. Thank you so much for the wonderful product.
PS: I think there a small bug in the sources you shared, if searching via audible.de, it will still set WWWAUDIOFILE to .com domain but with german ASIN, which won't work.
