Press the button in the bottom left-hand corner to make sure you've joined video on the call. No one can see me: If you can't be seen - and can't see yourself - start by checking you've started video on the call. Muting the mic can resolve the problem or identify which participant(s) are causing the problems. It might be that the microphone is too close to the speakers, it might be that someone is using a phone and computer or that multiple computers are too close together. There are echos or feedback on the audio: This usually happens when a mic detects audio coming from the speakers. This option is in the bottom left-hand corner of the screen share options. Otherwise the only sound people will get is that coming through your mic. There's no sound when sharing a video/YouTube: If you want to share video content with sound via screen sharing, you'll need to tick the 'share computer sound' option when you share your screen. If it's a one-off problem, there's likely nothing you can do about it except wait for the problem to pass - you could try stopping all other activity on your connection to let Zoom have all the bandwidth available. This is definitely worth doing if you always have a connection problem on Zoom. If you're using Wi-Fi, see if you can plug into a wired connection instead, as it's likely to be more stable than Wi-Fi, or move closer to your router. It's worth running a speed test - just Google speed test and you'll get the option to run a quick test where you can see if there really is a speed problem. This is a local connection problem so the first thing is to check your Wi-Fi connection or wired connection. Zoom says my connection is unstable: Unfortunatly this happens from time to time.

If that doesn't solve it, check if there are any software updates for your computer. If you're still having problems, try restarting your computer. My app keeps crashing or closing: First of all, do both of the things above.

You'll usually be prompted to update when you open Zoom if there's an update, but it's always worth checking, as some features change between updates. Make sure you're using the latest version of Zoom: There have been a number of Zoom updates recently, the latest version at the time of writing is Zoom 5.9.3, so it's worth checking that you're using the latest version of the app.
