The Resistance was established by Leia I think about six years before TFA. But Poe only joined something like a year beforehand. So we’ll either see them stretching the limits of what they’ve previously established (I guess there aren’t any exact dates in the material related to Poe), or they’ll just set the show within a year of TFA, which is possible, but seems tricky.
Give them a few years and the nuEU will be like this: https://www.youtube.com/watch?v=uOCBrYgBpjQ
