I have several characters, including this one, that do not show up on my profile like at https://worldofwarcraft.blizzard.com/en-us/characters. I noticed this because on sites that pull character data some of them are not working. I have data sharing enabled and has been for a long time. But probably 6 of my characters are suddenly not showing up or sharing data properly.
I can play them in game fine
Try logging in and outa forums a few dozen times.
It’s not just a forum thing. It affects sites that use my wow data to track mounts and stuff like simplearmory.
Some of the characters are actually showing up, and it is the ones that show up on the wow site. So it’s like certain characters are just not being sent in the API.
edit: Whelp, now this morning it seems to be working. That was weird lol
Unfortunately the forums and therefore the websites that pull data from the API can be a little finicky sometimes lol
ETA glad it behaved this morning for you
