He said he answered questions. Seems like his answers were useless since they kept asking. And why was he answering, and not someone from the team? This is classic situation in onboarding new devs on a team - the solution is to assign a dev to pair program with them for few days, that way it's either immediately visible they can't do the job and you bring that to the stakeholders, or they make a PR, nothing in between.

1 month is no time to expect great results even with onshore employees coming into your office, much less remote guys in a nonstandard difficult project. They probably meant they are finally beginning to understand it.

This is not "a team", it's a bunch of new developers in the authors' team and treating them in any other way is a serious leadership mistake. The author is wasting his employer's money.
