"Palace insiders are worried that she will be a loose canon," a source told Radar.
The main reason? "They are very aware that the former blogger has more experience with this than they do, but they want to make clear that once something has been posted it cannot be removed," explained the source, adding, "The experience of using social media as a royal and as an actress is very different."
As Radar reported, Meghan recently shut down a secret Instagram account she had created to follow friends and others without anyone knowing.
Now, the royals "are hoping Meghan obeys the rules or else the new account will be removed from her," said the source. "They are encouraging the couple to not post directly,
but rather allow the staff to do that."
And when the 37-year-old Duchess of Sussex does have something to say, she is going to have to at times bite her tongue — or face the palace's wrath.
"This account cannot be a method for her to respond to everything she doesn't like in the press," said the source. "They are not going to have a royal Instagram war on their hands!"
