VidyoConnect for WebRTC known issues

When using iOS 16 on a Safari browser, the video may appear distorted when the phone is rotated.

If this issue occurs, mute and unmute the camera, rotate the device to the opposite side, and/or rejoin the call in the desired orientation.

During a call where an application window is shared, if a user chooses another application window to share without manually closing the first window, the new application window is not shared.

When using macOS Ventura on Safari 16, if a user shares an application window, the preview of the shared window as well as the shared window itself appears smaller and surrounded by black space.

On iOS Safari, if you set your incoming calls to “Banner” rather than “Full Screen” and you answer an incoming phone call while you are already in a video call, your camera does not get muted.

To avoid this issue, we recommend configuring incoming calls as “Full Screen” instead of “Banner”. Alternatively, when you receive an incoming call, tap on the incoming call banner to make it go to full screen.

Occasionally, after 10 minutes or more in a call with certain iPad models, the voices of meeting participants begin to sound distorted. Some users have described this distortion as "robotic voice". This issue has been investigated and has been determined to be a Safari bug. For more information, see https://bugs.webkit.org/show_bug.cgi?id=241680.

Apple limitations cause some audio issues when VidyoConnect for WebRTC is used Safari on iOS 15. For more information, see Alert: Audio Issues with Safari on iOS 15.

Sometimes when using Safari version 13.1.x no audio is sent or heard. Workaround: Audio issue is resolved when using Safari Technology Preview 111 or Google Chrome version 83 or later.

When using iOS version 13.5.1 with Safari sometimes after several minutes in a call, the audio becomes choppy and/or a clicking sound is heard.

When accepting an incoming cellular call while on a VidyoConnect Native WebRTC call with a remote participant, the camera is not displayed as muted for the remote participant.

Repetitive Safari microphone permission pop-ups are displayed after the user has previously denied this permission.

A black tile occurs for a remote participant when switching from one camera to another camera and back again.

When a Sennheiser headset is connected, the Firefox browser transmits audio on both external mics (e.g., the built-in mic on the camera and the mic on the Sennheiser headset) during a call.

When using the Firefox browser, TURN relay calls may fail and the “ICE connection failed” error message may appear.

When a user clicks the … button near a name in the VidyoConnect left panel, the stethoscope indicator is missing.

Due to a limitation with the Firefox browser, if a user opens the application share list and then changes the name of an app, the app's name is not updated on the application share list.

Due to a limitation with the Firefox browser, the application share list does not update in real time; therefore, if a user opens a new app, they will not see it in the VidyoConnect share list unless they relaunch Firefox.

When using Firefox, the video displayed in the participant’s tile may not be from the camera selected on the Device Settings screen.

Due to a limitation with the Firefox browser, even if multiple audio output devices are connected, only the system default device appears as the speaker and ringing device on the VidyoConnect Device Settings screen.

If there are no lines available on the portal when a VidyoConnect guest user tries to join a call, the guest user will receive the erroneous message “Unable to join the conference. Please contact your administrator” instead of the correct message “Unfortunately, all lines are in use. Please contact your administrator or try again”.

If a logged-in VidyoConnect user tries to log out during an ongoing call, that user will receive an “Application Error” message.

If a Firefox user joins a call, shares content, and then edits the shared content, the other participants in the call will not see the edits.

If a Firefox user joins a call as a guest and then gets disconnected, after refreshing the browser, that user will receive a message saying the server is full and asking them to “Try again”. If the user then clicks the “Try again” button, the Firefox browser icon will keep spinning and never load the page.

When using Firefox, headsets do not appear in the list of available ringing devices on the Devices page.

When a user who is using Firefox on Ubuntu 16.04 OS starts sharing an application, the application is not brought to the foreground.
