Just listened. I think your albyhub problems are related to private channels.

The channel you open to their provider should be public "for podcasting".

Also verify your node is visible on the network. Is this it? (1 year old, 0 channels?)

And of course that LND is configured to receive keysend payments.

Can we help?
