SUF shows in my curseforge but is not showing up or working in game.  Literally not showing in my addon list in game.  TBC Anniversary.  

after bc prepatch it stoped working for me too. there where few updates over the day. once was from the author i guess with link to

mega.nz   https://mega.nz/file/ZDZWRDaQ#sdBm8-RS1_SHW65Dzg3LCgqfF0hWw7UkAdWomp_0WHc

download the file and extract manually in your (anniversary) bc-addon folder. (overwrite the files)

worked for me, while old settings was still on.

after that dont update suf over curse forge. sadly this happend to me this day and i had to re-extract the file again ^^

sry for bad english --> me german ^^

hope this will help

Got the same issue, stopped working in BC after I did /reload (working initially when installed).
Also, not clicking that guy's link.
