Audio disappeared for scriptures and CFM

I have used the Gospel Library app for years.
The headset for the audio option no longer appears. The app shows I have the scriptures and CFM in my dowloaded media.

Please use the Feedback link or button to report that problem to the official support channel.

I am seeing the same problem (no audio) nearly every time I try .
LDS library
iPhone
7.7.0 19981
Audio is either not available (no headphones icon)
Or selecting the headphones icon is non responsive
Tried Force abort of app, reboot iPhone, reinstall app
But these actions do not correct problems
Audio nearly always not available in scriptures, hymns, conference talks.
