I have a currently active session on my andrioid phone which I am trying to sync with an android tablet. I logged into Sync on both devices, then went to History > Sync devices on the tablet. It says "0 devices" under "Synced Devices". I click that and it prompts me to "get started" with a big orange button, no matter how many times I have already logged in. When I click it, it loads a page of sync settings which IS already logged in. It shows my account email and that Sync is "enabled". Open tabs are checked. But the tabs never sync. If I go into History on my moble it shows "1 device" under "Synced devices". It says "Last synced 1 minute ago". Still, neither device shows any tabs from the other device.
