Streaming playback issues after updating the TV from webOS 23 to webOS 25.

Good day!After the update to Software version 33.31.66 (webOS25/10.3.1-3101) LG TV UR78006LK (s/n 309MAGPBRE67), we noticed a deterioration in our application. Problem with playing DASH stream - streaming can start to be lost and after some time select “Streaming chunk error”, and for example a stream that only has Single-representation DASH stream doesn’t play, they immediately release “Streaming chunk error”. Tested with different networks, with different DNS, additionally noticed if we repackage the single-representation DASH stream into the multi-representation DASH stream, then the stream starts to work.Before updating, there were no issues with the stream streams in our app. We have also received similar complaints from customers in support of the issue after the TV upgrade to Software version 33.31.66.From the test TV, collected a log of mode debug during app trouble. (attachment log)Please tell me what this Software version update was about? How can it be fixed? Has anyone else been experiencing this problem?Once again, we would like to point out that this problem arose immediately after the update of Software version TV.
