VidyoClient for WebRTC JavaScript Library Version 21.4.0 LA - known issues
Key	Summary
IOWEBRTC-2218	When using VP9, the application reacts too quickly when there is a change in the available outgoing bandwidth which, in some cases, unnecessarily impacts the send resolution.
IOWEBRTC-1921	Video tiles that drop from calls due to network conditions sometimes do not get restored when the network conditions improve.
IOWEBRTC-1906	If a call participant with more than one camera or microphone disconnects their active device while their camera/microphone drop-down list is open, the drop-down list doesn't update to display the remaining camera/microphone.
IOWEBRTC-1861	When using iOS 14, audio artifacts can be heard for a few seconds after the remote participant starts speaking.
IOWEBRTC-1860	When using Safari Technology Preview 121 on a Mac with an Intel processor, users are unable to share content.
IOWEBRTC-1784	Audio lip-sync is delayed on iOS Safari after flipping the camera, muting and unmuting, or putting VidyoConnect in the background.
IOWEBRTC-1705	Occasionally, Chrome encodes at 10-15 fps even when the network is unconstrained.
IOWEBRTC-1673	On Macs with dual-core CPUs, when the "Google Chrome Helper (Renderer)" process goes beyond 100% CPU, Chrome detects a CPU limitation and lowers the encoding resolution.
