i don't know, but i've realized that i can no longer post screenshots in the art community,i'm not sure if it's a bug,but i can post screenshots in the other communities but not in the art community, i hope they fix it eventually.

It's not a bug. Now you can only post game screenshots on its respective community, or related. For example, you can post StreetPass Mii Plaza or Miitopia screenshots on Tomodachi Life community. They could make it so you can upload Art Academy screenshots here for example tho.
ok, but Art Academy and other art apps for Wii U don't have communities on Miiverse.
Likewise, i think i can post screenshots here in this community.
Yes, it makes sense.
