Fans raced to Twitter to share their thoughts, with one writing: "No way! I am so incredibly impressed by these two!" whilst a second penned: "Netflix you're spoiling us. Oh my god love love love it."
"I can't wait to watch this and I'm so proud of Harry and Meghan and the work that they're doing," enthused a third, and a fourth added: "One thing Archewell has mastered is giving good content with a purpose."
Meghan and Harry's surprise project comes after the couple caused an online sensation with their bombshell Netflix documentary titled Harry & Meghan.
Harry & Meghan dropped earlier this month
The three new episodes, which dropped on 15 December, featured a number of shocking claims by the couple, from Harry's details of screaming rows with Prince William, to claims he was blocked from seeing the Queen, to their "cold reunion" with the royals and allegations of "institutional gaslighting".
Elsewhere in the explosive volume, Prince Harry blamed the press for his wife Meghan's miscarriage. He revealed: "I believe my wife suffered a miscarriage because of what the Mail did… I watched the whole thing."
