I can import an OPML file and the feeds show up.
But I don't get a list of articles when I open a feed, even after "Update".
The log shows no errors but says e.g. "Subscriptions::parseXml(). No new articles since ke tammikuuta 22 22:54:33 2020 for subscription 696eb7d1-d2ed-439b-a8cc-e55bbdd560dc"
Is this expected behaviour or am I missing something here?
I would like to see all articles to date!

edit one day later:
OK, there's at least one RSS feed that has new articles, but they still don't show up.
The feed list is populated (through the OPML import I guess), but clicking on each feed only shows "No articles".
