Homey pro 2019 no web acces

Hi all,

I have a pro 2019 with different devices and flows.
When I login through phone/app everything is fine.
But when I use the browser (Google Chrome on several laptops) my devices and flows stays empty. I can see all my rooms/locations but everything is just empty.

Any idea why the Pro is not syncing with the web app?

What am I missing?
