I've had HLS switched on since @maddox was talking about how much better it was. Seems like remote streaming on my phone has gotten better. However I think I may have found an issue. I have a feed from BlueIris that I include in my custom channels. I couldn't get the feed to work at all. I switched HLS streaming off and it works fine now. I included a snip of the logs below and also submitted diagnostics from the client. The first part shows the failure and the latter part shows where it works after switching off HLS.
