Although there was no plot progression, but we got to see a lot of things
1. Naruto analysed Kaguya and now knows that her weaknesses comprises of taijutsu and diversion (because she is a bit senseless, which makes it seem like BZ is telling her the best things to do)
2. We got to see 5 tails rile Naruto's physical chakra so that he could break out of the ice that Kaguya put on him. Not only that; but Kurama modified Naruto's chakra just like before, so that the difference between the original Naruto and clones are not easily spotted…. Naruto is in fact better in Taijutsu than Kaguya who is meant to be a goddess.
3. It is not the real Naruto that went into the other dimension, it was the clone that was with Obito that got sent to where Kaguya was; in order to distract her while Obito and Sakura were waiting in Obito's dimension as a diversion… However, I think the real Naruto has entered that dimension as well but he's currently heading to Sasuke.
4. Naruto is almost as fast as Sasuke's shunshin-like eye technique; where as Sasuke makes a jump through his new rennigan, Naruto uses base speed and reflexes to move swiftly.
5. Kaguya is truly the ancestor of Kimmimaro, who is also been known to be part of Kaguya's clan, and there is an incredible resemblance between them, including the bone technique, which might be unique to their clan as a special attribute.
I wish we had more pages, but we all have to wait another whole week. Can't wait!
