I'm an adult member of an Apple Family Sharing group, but I no longer have contact with the family organizer and I don't own an iPhone. I tried signing in through a web browser and viewing the family members, but there's no visible option to remove myself. Is there another way for me to leave the group, or does the organizer have to remove me?

Adult members can generally leave Family Sharing themselves; child accounts are the ones that can’t leave independently. Since the browser view isn’t showing a leave option, try accessing the Family Sharing settings from an Apple device such as a Mac or iPad. If the option still isn’t available, Apple Support may need to remove you, or the family organizer may have to do it.

I’m definitely an adult. I checked the family page in a browser, but it only lists the members and doesn’t give me any way to leave.
