App is not showing pre-market and after-hours share prices.

Last week, my Seeking Alpha app was showing a total market collapse in the pre market when it would show -share price for all the stocks in my portfolio unless it  posted an activity. That seemed to have been fixed until the last 3 trading days. 

Lately, it shows no activity in the pre-market and after hours market. 

The Nasdaq site shows that it's the app that is accurate.
