I’m happy to adopt a new podcast app if it has sponsorblock natively or through a plug-in. Otherwise let me know if there’s some other way to make it work. I don’t see why it wouldn’t work as all of the segments tagged for skipping are crowdsourced which would also work for Podcasts.
I used to use WeCast, it had a community driven block much like sponsorblock. But it was a long time ago, I couldn’t find it on Google Play so I don’t know if it’s still active.
