I'm just listening to the Rolling Stone interview for the first time:

At the 11:42-mark Stevie says, "We were supposed to go into rehearsal in June, and he wanted to put it off until next November. That's a long time."
It's unclear whether she's using the word "it" to refer to the rehearsal or to the tour. But in any case, despite her use of the word "next," I think she means November 2018 – not November 2019.
Of course, we would later hear that Lindsey was willing to drop his request for any delay at all. But by then, it seems to me, they had already started thinking about kicking him out and his agreement to accommodate their schedule was effectively "too little too late."
