DASH Streams trick mode, doesnt seem to follow the spec

Roku Streamtester player doesnt seem to play video when using trickmode as mentioned here:https://dashif.org/docs/DASH-IF-IOP-v4.2-clean.htm#_Toc511040730

can anyone share a sample working DASH stream to test out trickmode in dash streams? i want to test it out on the StreamTester app.
I used the below stream and trickmode doesnt seem to work with it:

http://dash.edgesuite.net/akamai/bbb_30fps/bbb_with_multiple_tiled_thumbnails.mpd

But, if I play this: [https://dash.akamaized.net/dash264/TestCasesIOP41/MultiTrack/alternative_content/4/manifest_alternative_Essentialproperty_live.mpd](https://dash.akamaized.net/dash264/TestCasesIOP41/MultiTrack/alternative_content/4/manifest_alternative_Essentialproperty_live.mpd) the thumbnails play instead of the video.

Not sure what is going on.

Were you able to resolve your issue ?
how did it play out ?

Roku now support getting thumbnails from manifest, you can check their samples.
