I get this with NewsBlur 4.6.1 on an iPhone 6 and iPad Air, both running 8.1.2:
- Launch NewsBlur
- Go to All Stories
- Tap on any story
- Use the Share button to share it (no comment needed)
- Swipe to the next story
- Swipe back to the previous story. The title shown is of the story you just shared instead.
If you swipe away at least two stories, then back to the original one, it correctly shows the original title again. I’m guessing this is because NewsBlur seems to cache the previous and next story, so you have to go two stories away before it will rebuild the story instance.
