Key	Summary
IOWEBRTC-2526	In a call with custom layout, the remote participant's self-view tile no longer blinks when their video tile gets rearranged.
IOWEBRTC-2520	Rearranging the tile that is displaying the remote share no longer results in a black tile.
IOWEBRTC-2489	Enghouse Vidyo now supports a full-screen pin mode. The image will now be cropped to fit the browser window dimensions, resulting in full-screen video when the browser is maximized. This feature is enabled through this advanced configuration setting: vidyoConnector.SetAdvancedConfiguration({ pinnedParticipantDisplayCropped: true });

Known issues

VidyoClient for WebRTC JavaScript Library Version 21.6.1 LA - known issues
Key	Summary
IOWEBRTC-2441	On iOS 15 Safari, participants experience low sound output in calls. This is due to a known Apple bug in Safari/IOS15: https://bugs.webkit.org/show_bug.cgi?id=230902 Workaround: Connecting and disconnecting a headset can sometimes fix the issue.
IOWEBRTC-2423	A muted microphone may appear to be in use, causing users to think that the microphone is in use when it is not.
IOWEBRTC-2402	On iOS 15 Safari, if a user switches to another incoming call during a video meeting, the remote video is not restored after that user returns to the meeting. This is due to a known bug in iOS 15: https://bugs.webkit.org/show_bug.cgi?id=230537
IOWEBRTC-2339	On iOS Safari 15, if the mobile user puts the video meeting in the background or switches to another browser tab, sometimes the video does not resume after the app is brought to the foreground. This is due to an iOS bug, which is fixed in the iOS 15.2 release: https://bugs.webkit.org/show_bug.cgi?id=230538 Workaround: Mute and unmute the camera.
IOWEBRTC-2274	In some cameras with zoom, the zoom function does not work. This issue occurs in VidyoClient binary 21.6.0.4 and earlier.
IOWEBRTC-2222	When a mobile device is in Portrait mode, the browser rotates the applied video constraints and switches to Landscape mode. This has been investigated and determined to be the behavior for the current Safari and Chrome browsers.
IOWEBRTC-2218	When using VP9 codec in desktop or mobile Chrome browsers, the application reacts too quickly to bandwidth fluctuations, which can sometimes lead to reduced outgoing video resolution.
IOWEBRTC-1942	On iOS, when a user starts sharing their camera (selects the camera as a source for content sharing), the video stream stops and remote participants see a black video tile. This is due to an iOS bug: https://bugs.webkit.org/show_bug.cgi?id=179363
IOWEBRTC-1921	On iOS Safari, video tiles that drop due to network conditions sometimes do not restore when network conditions improve. Workaround: Drop off the call and then rejoin.
IOWEBRTC-1863	On iOS Safari, low video resolution can occur if a user puts the mobile app in the background during a call, and then brings it back to the foreground.
IOWEBRTC-1861	On iOS 14.4-14.7.1, crackling audio noise can be heard during the first two seconds of the remote user audio stream. This is due to an iOS issue: https://bugs.webkit.org/show_bug.cgi?id=219161
IOWEBRTC-1823	VP8/VP9 users with limits for receive/send bandwidth may experience fluctuations in frames per second (FPS) and resolution during video calls.
IOWEBRTC-1784	Audio lip-sync is delayed on iOS Safari after flipping the camera during a call. This is a known issue with Safari that cannot be fixed by Enghouse Vidyo at this time.
IOWEBRTC-1719	On iOS 14+, video continues to transmit during an incoming voice call.
IOWEBRTC-1705	Chrome browser sometimes encodes only 720p/10-15 fps, even when the network has enough bandwidth to support a higher frame rate.
IOWEBRTC-1673	On Chrome in macOS with dual-core CPUs, the resolution drops when the CPU idle is at 30-50%.
IOWEBRTC-1637	Occasionally, after one hour in a call, the voices of meeting participants begin to sound distorted. Some users have described this distortion as "robotic voice". This issue has been investigated and determined to be a browser bug.
