Describe the issue you are experiencing

Any changes to HA aren't reflected in the app or through browser when connecting to nabucasa url (*.ui.nabu.casa).

So no changes to dashboards are reflected and any updates to components or version updates to HA itself are shown. By that I mean that HA tells me that there is an update available but I have actually updated it.

None of these issues are present when connecting to a local IP address.

I have deleted dashboards and created new ones but none of these changes are visible using Nabu Casa url. F.ex the deleted ones are still present.

Describe the behavior you expected

All changes in the UI should be shown when connecting to the HA instance using Nabu Casa

Steps to reproduce the issue

1. Do any change in a dashboard and save it
2. Log on to your instance through a browser with local IP and check if the change is made
3. Log on to your instance through the app or browser using Nabu Casa url and check if the change is made
