My firefox switched over without any issues.
Alas I had to restart chrome to make it work properly.
If you are unable to clear the information chrome wants to remember about the old server, then you can solve that, temporarily or permanently, by opening https://kano.space/ instead of https://kano.is/
It of course points to exactly the same server and replies with the same information, but as I mention on the web home page:
It's a 'backup domain' in case you ever have any problems using the kano.is domain
I've so far not noticed any problems with other devices, but again, if anything you connect with wont connect to the new server due to only remembering the old server information, just switch to https://kano.space/
Mine On!
