some RSS feeds are not detected
Briar gives an error when importing Some feeds, specifically several on Substack, e.g. https://edwardsnowden.substack.com/ or https://cryptobeat.substack.com/.
Substack seems to have /feed , /feed.xml , /feed.rss , and none of those work for me in Briar. Substack's support said I should reach out to Briar since the substack feeds work in other readers they tried.
I haven't had an error on other feeds I've tried, it imports both RSS & Atom from Tails' blog (https://tails.boum.org/news/index.en.rss or https://tails.boum.org/news/index.en.atom) It also works with Signal & FlowCrypt's blogs (https://signal.org/blog/rss.xml and https://flowcrypt.com/blog/feed.xml).
