Is there any potential reasons why daily session bitrate receiving decrease in the middle of the cal
One participant told us the video quality was very low. We look into the session log and we saw that the participant's bitrate receiving was unstable.
Is there any reason why this could happen? or is it just a bad internet connection the participant had?
We also want to know the recommendation to handle such situation (i.e., sacrificing frame rate for video resolution, showing user a warming message that the internet connection is bad).
Thanks!

H @TomohiroMaeda , there are a lot of factors that affect how much bitrate is used during a call and how that affects the call quality. Network connections can be highly variable and without more information it's hard to say what the exact caused the "spiky" bitrate in this session. In terms of how best to handle instances where users have weaker internet connections, there's a few things you can do.
It's important to choose resolution and bitrate settings that match with your intended use case as well as the types of devices and connections that you expect for your users. For example, if you expect users to always join from a mobile device, selecting smaller resolutions and lower bitrates can reduce the load on phones connection via cellular networks. Alternately, if your use case is designed for desktop devices with that will always be using high-quality cameras with wired connections for example, you have more freedom to increase the quality of the video and audio streams.
We have lots of resources on how to pick simulcast settings that should work best, here are some examples:
