So I recently noticed that the Portfolio category is not listed in the “front page” of the Collaboration category. Here is a screenshot sharing explanation this:
I believe this started happening a few weeks ago, but I’m not entirely sure. Ever since the Asset Marketplace got removed, the Portfolio category haven’t been visible on there.
If the bell icon is crossed out then that means you have muted the category therefore it won’t show up unless you’re specifically searching for it. Much like bulletin board the category is really only meant for specific people (portfolios is mostly meant for people looking to hire someone).
The entire #collaboration category was muted by default at one point but that was changed. However I think #collaboration:portfolios was kept muted by default. Not sure about that though because I changed it myself.
