I can’t pin it down exactly, but I went through my notifications. One was in a thread of a user I have blocked now. I then accessed the next notification, which was in my own thread, and Spectrum showed my own thread’s OP as blocked. Some experimenting later I was back at the blocked user’s thread and it was not hidden as blocked. So the blocked status kind of gets stuck sometimes and carries over from one thread to the next.
Any chance you were able to get some more specific reproduction steps on this one? Having trouble reproducing it on our end.
