Problems with Digital Signage

I am using a Fire TV stick - purchased last week - to send digital signage to a television using the Proclaim Sign app.  I have a strong wifi connection with no filtering or blocking of ads.  I have two problems.

1)  Most videos don't load at all.  Still frames do fine, but I get an error saying "The Media Could Not be Loaded, Either Because the Server or Network Failed or Because the Format is Not Supported."

2) The videos that do load only do so in a broken way.  A portion of a still frame from the video fills the bottom right 1/4 of the screen.  

The test stream I am using can be found here:  https://faithlife.com/grand-ledge-church-of-the-nazarene-presentation/signs/main
