The Sussexes were forced to relinquish their Instagram account, Sussex Royal, after leaving their senior royal roles at the end of March.
It has meant all of their subsequent work for charities in lockdown has been promoted via other pages.
Meghan’s adorable story time with baby Archie was only revealed on Save The Children’s Instagram account and, most recently, their work with LA community group Homeboys and Homegirls was also unveiled on the charity’s page.
And royal commentators Lizzie Robinson and Chris Ship believe this has proven to be quite the frustration for the couple.
Speaking on ITV’s Royal Rota podcast, she said: “Their platforms are now inactive or dormant so they're having to rely on organisations like Homeboy to put the photographs up and alert us to the work they're actually doing."
Mr Ship, ITV’s royal correspondent, added: “They must find that quite frustrating, not having their own social media channels.
“You're less in control, aren't you?
“They were criticised for setting up their website and calling it 'Sussex Royal’.
“I'm sure work is going on about setting up their own social media platforms, but, at the moment, they are without."
Lizzie agreed, adding that the “only way we can hear from them or see them is if people do it on their behalf”.
"So, like when they did their Save the Children reading for Archie's birthday, that went on the Save the Children site,” she continued.
"They've done the volunteering now, and that's gone up on Homeboys and Homegirls social media."
Homeboys and Homegirls has been delivering food to the most vulnerable during the coronavirus pandemic. To help out, Meghan and Harry were filmed taking part in a cooking programme.
It comes after it was claimed the pair’s “reckless” habit was “monitored” by the Queen.
