LingQ app audio not loading

Trying to listen to the mini stories, and they just aren’t loading. I have tried:

-restating the phone and app
-going into the lessons (instead of the playlist)
-multiple lessons

stories 1-4 are working 5-8 are not. any suggestions on a fix?

Are you using iOS or Android app?

Android. looks like a reinstall for the app solved the problem.
