NWS Warning Polygons not Populating

I am using RadarScope Android version 5.5.7

NWS watches, special weather statements, convective outlooks, and mesoscale discussions display on the map when the layers are selected. Warning polygons do not display despite the warnings layer being selected. 

In the alerts menu in the top right, only watches and statements populate with any data. The warnings section lists “None” despite several active severe, tornado, and flash flood warnings.

Any advice is welcome.
