Self-service first
Solve common device and connection problems without exposing an account.
For a blank camera or silent microphone, check site permission, operating-system permission, and device selection. For freezing or dropped calls, reduce competing network use and keep the device on one stable connection.
Write down the symptom and the last successful step before changing settings. This makes it easier to tell whether the fix worked and gives support a reproducible path if the issue remains.
- →Use the camera guide for blocked or wrong devices
- →Use connection help for freezing, delay, or dropped calls
- →Do not send passwords or one-time codes
