Se Puede Usar Whatsapp En El Apple Watch

I'm having trouble playing online with my friends in FIFA 2023 on my Xbox Series X. I've already added them as friends, but when I go to play Friendlies online, it prompts me to add them again as if we're not already friends. Is this a known issue? Is there a fix for this? I really enjoy playing with my friends and it's frustrating that we can't seem to connect online.
