Question and bugreport for Fountain

Question: how do I import custom rss feed? Not opml, I have a feed URL and I can't seem to find a way to open it

Bug report: Lately, fountain forgets where in the podcast I stopped listening. I listen in the car, get out, put on headphones, open fountain and it starts where I was before listening in the car. Sometimes it forgets between two listens. Very annoying. I'm on GrapheneOS, I don't kill the app or anything weird. This is a new problem, it wasn't like this before.
