Podcasts lists are empty - newly installed volumio

Hi, question from Volumio newbie about how to get the BBC podcasts working.

I installed the latest volumio (2.587) on a Raspberry Pi 3 B with a touch screen and wifi to local LAN.
Works perfectly for playback of .flac files from NAS and also web radio, e.g. BBC2 and BBC4.
I installed the optional podcast module, removed all podcast sources except for BBC, opened the Podcast option in Browse mode, see the icon for BBC Radio Podcasts, click … and select Update Folder - see a brief message about ‘podcast/bbc Updating Music database’, click the BBC icon, see a list of icons including BBC Radio 1 Podcasts, BBC Radio 2 Podcasts, etc. select any one of these, click the options and select Update Folder, see a brief message about ‘podcast/bbc/radio4 Updating Music database’, click the same icon and see an empty screen with a title e.g. BBC Radio 4 podcasts.

Thanks for any hints or tips!

After further reading I found out how to generate a log:
logs.volumio.org/volumio/DKKvbWe.html
and noticed that the last entries include:
Jul 10 14:22 : exception: Failed to access /var/lib/mpd/music/podcast: No such file or directory

So I connected via SSH and created the missing folder:
volumio@volumio:~$ ls -l /var/lib/mpd/music/
total 8
lrwxrwxrwx 1 root root 13 Jun 11 21:06 INTERNAL -> /mnt/INTERNAL
lrwxrwxrwx 1 root root 8 Jun 11 21:06 NAS -> /mnt/NAS
lrwxrwxrwx 1 root root 8 Jun 11 21:06 USB -> /mnt/USB
drwxrwxrwx 2 root root 4096 Jul 10 15:01 podcast

but still no joy ;-(

Hi, just wondering if this is the right place for this type of question?
If not, is there a better place?
