I just followed @andrew.sprk.so s steps and it worked for me so lets see if he can help or if the @sprk.so team says something, because sadly if that doesnt work i dont know how can i help you

are you trying to change them in the bluesky app or in spark? I had to change them in the bsky app and then it were automatically changed in spark. If that isnt working now i dont know what can be done :(

This can be done followimg those steps bsky.app/profile/andr...

For now you can edit your profile or follow people by logging in to your spark profile on bluesky. Thats how i changed my profile and started following people. Hopefully in the future it will be way easier 😅
