In the past few days/weeks I've bookmarked both the Star Trek and Star Wars threads in Debate and Discourse.
Both of them, bookmarked or not, will not recognize that I've read the posts and continue to bring me to the first page whenever I try to read them.
Tried it with the Trek thread a few weeks ago and gave up on it without complaining. Yesterday found the same issue with Wars thread, and again trying to read the Trek thread. Using Chrome on both PC and Android phone.
It's a little frustrating, I'm not going to lie.
