They officially stepped down after carrying out their final royal duties in March and have since relocated to the States.
Recently, fans were left scratching their heads when the couple sent a letter that still included their royal monogram.
They sent a letter to the charity StreetGames, thanking them for playing their part in helping to deliver meals across London.
Those with an eagle eye were quick to ask why they still used their royal seal.
Well, we have the answer for you!
Wow! Thank you so much Harry and Meghan for your kind words and your continued support for StreetGames and the brilliant local organisations working to support their communities in these challenging times pic.twitter.com/4h9bMGTuTR

They can continue to use the royal monogram because Prince Harry is the son of an heir apparent, Prince Charles.
After the couple’s wedding in May 2018, a coat of arms was created for Meghan Markle and she was assigned a Coronet.
They described it at the time: ‘A Coronet has also been assigned to The Duchess of Sussex.
‘It is the Coronet laid down by a Royal Warrant of 1917 for the sons and daughters of the heir apparent. It is composed of two crosses patée, four fleurs-de-lys and two strawberry leaves.’
The coronet used by Meghan and Harry is the same as that of Prince William and Kate Middleton, as both William and Harry are the sons of an heir apparent, Prince Charles.
The main difference is that Meghan and Harry have their joint M and H under the crown.
In the agreement with Queen Elizabeth Harry and Meghan formally retain their HRH styles, but they no longer actively use them.
