Most of my Newsblur usage on iOS is scrolling the All Stories section of my feed, and more often in the last few months scrolling can get very slow and pause, and sometimes it freezes so I can’t interact with the app at all until it crashes and I have to reopen it.
The freeze+crash will happen at the same story in the feed, so if I close/reopen/force quit/reboot/whatever and scroll down All Stories to the culprit article, it will freeze/crash again. It doesn’t appear to be stories from any one particular feed, but when a Crashing Story does come into my timeline and it first appears at the bottom of my screen (where new stories scroll “up” from), that is when the feed crashes. I can scroll to the story above the Crashing Story just fine but as soon as I scroll down one more article…bam.
