In a nutshell, I have an IG account I am re-branding, and want to change the Bio. In the past, I have opted to create the bio in notepad (iOS) to utilize Emojis, and more streamlined formatting. However, I noticed for the past few weeks I have not been able to copy and paste on this specific account. However on my others, they all allow it.
I am using the same iOS device to manage all the accounts, so I have to believe its some restriction that has been placed on this single, specific account.
