Open [Chrome] Renaming your current Device

So I had a previous device called 'Macbook' but I'm not sure how but Join decided that this device was different and created a new device called 'Chrome'.

'Chrome' worked and I can send and received pushes to it.
'MacBook' didn't seem to work anymore.
So I went to https://joinjoaomgcd.appspot.com/ and deleted both 'Chrome' and 'MacBook' so I can 'start fresh' per se.
Unfortunately Join didn't refresh this list with the one it's currently using.
I tried Diagnostics running from Chrome and it would hang at 'Sending Pushes to server'
In Join settings, it still says 'This device: Chrome' and I can still receive and send pushes.
I can see 'Chrome' in other devices but not in https://joinjoaomgcd.appspot.com/
I don't see 'This device' on 'Chrome' though.

So it all works but diagnostics is freaking out and I have no way to rename my device globally.

 

Uninstalling and Re-installing fixed it, though I had to re-setup every one of my computers using Chrome because the synced Extensions uninstalled Join from every device using Chrome.
A bit frustrating but it did fix the issue.
I wish there was a sort of 'reset' button on the extension and the app.
