Original version of Edge is the only browser on Windows that native support HLS , but until now the new Edge doesn't support it.
Will you add it?
I don't have definite yes or no, but I do know this was brought up not to long ago and the engineering team is still looking into this.
As always clicking the Smiley Face on the top right corner of the browser to submit feedback does make a difference.
Thanks for your time and feedback,
I joined the community today. I see in the version I downloaded today (ver 79.0.309.11 ) that HLS is working. I have been looking for a version to test with security cameras. Tested today and it works.
