Late Export for You: Although Stitch & Ai was produced in English, the original English version wasn't released anywhere until its Southeast Asian debut in February 2018. Moreso, it didn't see release in any Western country until December 1, 2018, when it was quietly released on the DisneyNow service and app in the United States.
Missing Episode: The American release of the series excluded the ninth episode "The Phoenix" for unknown reasons.
From Lilo & Stitch: The Series, executive producers Tony Craig and Jess Winfield returned as director and voice actor, respectively,note although Winfield's role as voice actor is mainly a continuation from his involvement in the anime's English dub and Michael Tavera returned as composer.
Victor Cook, a director for both seasons of Lilo & Stitch: The Series, was signed on to this show and had some hand in production, but later had to back out early on due to other obligations, letting Craig take his place.
Role Reprise: Ben Diskin and Jess Winfield reprise their roles of Stitch and Jumba respectively from the Stitch! anime's English dub, effectively making them the current official voice actors for those characters in the franchise. Doubly so in Winfield's case as Jumba's original voice actor would die the month after this show aired in English.
Short Run in Peru: In a bizarre case of this trope, China, which this series was made for and was animated in, got this series first, but the Mandarin Chinese version is actually a dub. The English version is the original production (the characters' mouth movements are actually reflective of English speech) and was the basis for the original trailers that first promoted the show in China, but it didn't see release until over ten months after the show's initial debut. The American release was held back even further by almost ten more months.
What Could Have Been: A second season was discussed, but Tony Craig said that Disney was waiting to see ratings from other countries first before they would approve one. Since the show received little attention outside of China (with what little attention it did receive being incredibly mixed), was later removed from DisneyNow after about six months, and Disney's likely focusing more on developing the Lilo & Stitchlive-action remake, a second season of this series is most likely never going to happen.
