Hi we have two Roku apps one for old devices(in native bright script) and another for new devices(in scene graph). We stream videos with subtitles. We have subtitles file in srt/vtt files.
The problem is subtitles are not stable in all the devices. Some subtitles files works in Roku 4 and 1 but doesn't work with Roku premier plus. Some files doesn't work in any of the Roku models. We tried different ways to show subtitles like SubtitleConfig, SubtitleUrl and SubtitleTracks of ContentNode. What is best practise to show subtitles? Also is there anyway we can check a subtitle file doesn't work in Roku?

I got this working by adding some extra space/text where there is no text/characters below the time stamp inside subtitles like below 

1
00:00:00,000 --> 00:00:00,417

See if the type of line ending makes difference (LF vs CR+LF vs CR).
Also mention here which Roku player models (by model#) have the difficulties.

Its only empty space with timestamp which is causing the issue. 
Also the problem was there in almost all Roku models Roku 4, Roku premier plus etc.
