All the things that were disappointing with this chapter:
-No post-battle scene with Ywach's final words to Ichigo or Uryu.
-No explanation of who takes up the mantle to become the next Soul King so that the Seiretei doesn't break apart.
-No explanation of whether Aizen was killed or vanished on his own terms.
To be honest, I expected an all out battle (Marvel Infinity War style) between all of Soul Society--guns blazing with their new bankais with Ichigo at the head--and the illegitimate Soul King Ywach. I expected Ywach, beaten down and all out of options, to pull out Yamamoto's Bankai in a daring new cliffhanger. I expected Ichigo to finally unlock his true power, his final Quincy/Shinigami/Hollow form (because he's just barely tapped that power) and transcend all of his prior abilities, and surpass even Yamamoto's power. That's how he becomes the Soul King--because he's transcended everyone and earned that right. Because he's the most noble, pure-hearted character and is the best representative of all races. Because he's the main character. Would've been as good as Naruto, who became godlike, and damn better than him at the same time, since he becomes a god-king instead of a mere Hokage.
At the very least, I actually wanted to see Ichigo's bankai, either during the war or in a mock battle with any of the captains (Kenpachi included :D). Instead we get this "convenient" time skip, because the author ran out of creativity/passion and wanted a quick finish.
