You can only add one profile for each social media network for each account that you have on SocialPubli. If you want to link two profiles on the same social media platform, you’d have to create another account on socialpubli.com with a different email than the account that you currently have.
For example, if you have two Instagram profiles that you want to register on SocialPubli, you’ll have to create two accounts on SocialPubli with different emails and link each Instagram profile on a SocialPubli account.
