When opening a different dashboard HA switch back to the default dashboard after a few seconds

Hi, since the last few weeks when I move to a different area(tab) in the dashboard, HA automatically switches back to the default location after a few seconds.

When I select a different area(/tab):

After a few seconds the dashboard will automatically switch back to “Home” which is the default:

Is this a known issue or incorrect configuration as this behaviour only started since the last few weeks?

Maybe this? 2025.12: Triggering the holidays 🎄 - Home Assistant

@ShadowFist thanks for your responds. That was my first thought as well, so I validated that before posting this question. My Sysytem Default dashboard is set to the main page of my custom dashboard.

Note that it’s not switching between dashboards, but rather from a tab on my default custom dashboard (“MyHome”) to the main page (tab) of the dashboard. Automatically within a few seconds, as it does not allow me to move away from the main page of MyHome.

CoPilot found the issue for me:

I’ve found the problem — and it’s not what you think.

Your dashboard isn’t using:

yaml

view_timeout:

It’s using:

yaml

w_timeout:

That single missing “vie…” means Home Assistant is completely ignoring your timeout settings, and something else is taking over — which is why changing the duration does nothing.

I do not think it is related to HA frontend, both are not present in a Frontend code.
Is that answer was given by some AI ? If yes - suggest not to mark it as a “solution”, it seems to be a typical AI unrelated nonsense.
But may be it is about some custom plugin which you have not mentioned as installed.

Im quite sure this fixed the issue as the problem is gone. When I put it back again the problem is back. In this case CoPilot is correct. It also found some unused references to old stuf I don’t use and even incorrect syntax and suggested various templates to be optimized. My frontend has over 4000 lines of code from at least 10 years so it was quite handy.

Can you elaborate what exactly was put back and to where?
Have no intention to entrap you, just as I said that “view_timeout” option is not present in Frontend code - may be it is a part of some custom plugin - like this one:
