It was originally scheduled to conclude on 2 July 2017, in London, England, at Wembley Stadium, however on 30 June Adele announced via social media that she had regretfully cancelled her final two performances upon medical advice due to vocal injuries.

[15] The tour's Australian dates were announced on 15 November 2016; Adele would perform a series of special stadium concerts in market's five big cities in February and March 2017.

McNulty states that "Adele undoubtedly has the popularity to fill endless arenas, but maintaining the attention of thousands of people used to the hi-tech extravaganzas laid on by the likes of Taylor Swift and Beyoncé can demand more flashing lights, dance routines and hydraulics than any natural talent.

"[25] BBC News music reporter Mark Savage said that "Adele enjoyed a rapturous reception as she opened her world tour with an intimate arena show in Belfast."

In his four star review, Petridis noted Adele saying "I know some of you have been dragged along here tonight but I'm going to win you over", before concluding that "judging by the reaction as she finally disappears - on the same platform on which she appeared - she has managed it.

"[28] Nick Hasted of The Independent gave the show three stars, saying that "she tries soul moves over gospel piano, but owes more to Shirley Bassey than Aretha".

The Huffington Post's Ashley Percival gave one of the shows five stars: "By her own admission, most of her back catalogue is "fucking miserable", and I questioned quite how the Tottenham-born songstress would hold the attention of the packed O2 Arena without being able to rely on exhaustive dance routines or belting out some pop bangers to boost the energy.

But the second she emerged through the floor of a small B-stage uttering those immortal words "Hello, it's me", any concerns just evaporated — every single person in the room was in complete awe, and would stay that way for the entirety of the 18-song set.

"[30] David Smyth from the London Evening Standard said that "Adele shifted constantly from being a lightning rod for emotion to a light entertainer" in his four star review.

He also complimented the show's opening performance of "Hello", saying that "isolated, with her large band hidden behind the screen, [Adele] held the room without trickery — just one of the great singing voices.

"[31] Ludovic Hunter-Tilney from the Financial Times stated in his four star review that the show "had an old-school air of professionalism, sumptuously mounted and impeccably rehearsed."

Heather McNeill of The Sydney Morning Herald said Adele "was noticeably humbled by the massive crowd [the largest in West Australian concert history], admitting in her first many witty and warm chats with fans that she was a bit nervous."
