Actually this is an issue of the Subscribe button. It seems that the itpc URI scheme is deprecated in Catalina. Using "podcast://" works as indented. /CC @benzimmer

[flacchini14]

is there already a simple workaround for this issue? The podlove publisher already uses podcast://

Is there a possibility to configure the Subscribe button to use "podcast://" instead of "itpc://" ? I can't find anything in the documentation.
