com.amazon.android.uamp.ui.PlaybackActivity cannot correctly play an .m3u8 file

I'm trying to play in Fire TV app a .m3u8 file but the video freezes for a few seconds (audio backs) and then continues and after a few minutes it freezes again. The urlFile.json is pointing to the json below:

[
{
"id": "169313",
"title": "Live TV Channel",
"author": "Live TV Channel",
"utterance1": "Alexa, open Live TV",
"utterance2": "Alexa, open Live TV Channel",
"description": "Live.",
"duration": "14400",
"thumbURL": "https:\/\/negociostv-images.s3.eu-west-1.amazonaws.com\/negocios_512x512.png",
"imgURL": "https:\/\/s3.eu-west-1.amazonaws.com\/negocios.firetv\/negocios_hd.jpg",
"videoURL": "https:\/\/play03.gooru.live\/playnegocios\/_definst_\/5646-1603313320000\/playlist.m3u8",
"categories": [
"Directo"
],
"channel_id": "13454"
}
]

I need to solve this problem asap.

Thanks in advance!

Reproduce the freezes in PlaybackActivity using the supplied videoURL from urlFile.json and the linked .m3u8 stream. Then inspect the playback configuration and determine whether the issue is reproducible in the app; done means the live stream plays without recurring freezes and audio interruption.
