The story is not disappearing any more! I can see that it is refreshing and scrolling back to where it was. So problem solved.
When I go back to the list of articles in the feed, I can see that has refreshed too, and all the read articles are gone. Have to find my place again if I was picking out interesting articles in a long list, but not a deal breaker. I have no need to stay on the 13.x version now. Thanks.
It should be out by now, it only takes a few minutes.
I don’t know what to say to that except that I was checking the Newsblur app F-Droid page regularly from when I received your reply email, checking to see if the new version was listed, and it didn’t show up until about 30 hours later. I was refreshing my the F-Droid client app on my phone, too.
