This has to be a joke. Multi-device sync? Most people don&#x27;t know what that is.<p>They just want a pretty GUI, their friends to be on it, and an easy way to send videos&#x2F;photos&#x2F;voicemails&#x2F;whatever.<p>Granted, I&#x27;ve never wanted to send videos and sending photos works well on Signal right now. But until recently the GUI wasn&#x27;t very polished.
