Thanks for working on the dismiss for blocked communities and users, it looks great!

I just have one question:

Ensure that Subscribe/Unsubscribe accurately reflects the current state.

Does this only apply to the current post? (e.g., If I have multiple posts from a given community in the feed, but I subscribe to a community via a post card action, does the subscribed state apply to all other posts with that community?)

If not, then maybe a better way to handle this is to display a snackbar message when the subscribed action is successfully performed. I think the user will mostly understand that they have to refresh the feed to see that subscribed status.

Ahh, good catch, it did only apply to the given post. I replaced the update with a snackbar!

The only other options I could think of would be to (a) iterate through the whole feed and update all matching posts (might not be too bad) or (b) fetch the status every time opening the bottom sheet (wouldn't be great).

Just a few minor comments!

Should be good now!
