Hi,
This brilliant feature, the ability to mute activities, is missing from desktop (I believe its been in mobile for a year or two now).
Would love to have it on the website as well - I use it to reduce clutter on people's feeds, for example my inane commutes of which there can be several daily. Also for some content I think people wouldn't appreciate or expect on a fitness platform but that I still want specific people to be able to see.
