I think people are complaining that there was "no resolution" because they saw the previous arc as being this absolute foundation-destroying event sure to leave the protagonists adrift in Blue Yuri, and only an absolute miracle could repair that, and they're not seeing a dramatic miracle, so surely it's unresolved.
Whereas in reality, it was never that intense a thing. It was a relationship speedbump as happens in relationships from time to time, and after some event that puts things in perspective, they start moving again and it's fine. There was a resolution to the actual problem, just not the imagined one of the comments section.
