I am asking this questions for my employer. She has two businesses. Both have Instagram business accounts and Facebook business pages. She is posting on Instagram account number one and when she shares with Facebook it is sharing with account number number two's Facebook page. She tried to unlink the Instagram business accounts to temporarily solve the problem but she finds the option in Instagram settings to unlink and presses it to follow the prompts to unlink but then it doesn't unlink them. How can I help her fix this problem?
