Wikiradio (by Rai3 Italy) probably wrong adress service (old version antennapod work about wikiradio), don’t show the list about titles after choose new subscribe, there are 4 or 3 about wikiradio (because there are very lot titles when Antennapod work with wikiradio, but now nothing, good with other subcribe not wikiradio).
Thankyou for your attention.
