NBA League Pass recordings rarely work on Stream app

I'm an NBA League Pass subscriber. This season I've noticed that recordings of the NBA League Pass channels almost never work correctly when I try to play them on the Stream app on my iPhone or iPad — after a few minutes it's a situation where the video freezes and the audio continues playing, which never fixes itself. The recordings work fine when I watch on my X1 DVR, and recordings from other channels work fine on the Stream app; this seems to be specific to the NBA League Pass channels. Anyone else having this issue? Anything that can be done about it?
