Some settings are not applied

[Solarunit]

Home Assistant 2023.3.1, docker

Some settings are not applied, like Dark theme, or Always hide sidebar. Well, they would be applied only for a browser session. Is it docker limitation?

This is a correct behaviour.

I wish I could force these settings for HA in the browser, it's annoying to set them every time.

Imagine that you opened HA on a mobile client and then can select a different theme & hide a sidebar.

I have HA client app installed, no problem there, you never logout from it. I haven't tried a different theme, it's Dark.
Maybe the app should have its own settings?

Chrome after clearing a browser's cache, I have to login again

Yes, that's expected, you nothing can do with this, except a dedicated desktop app..

and then set a theme, number format, arrange sidebar items

this is my problem, I want persistent HA settings every time I login in the Browser.

I suggest you either to ask a question in Community (I would prefer this, may be you will attract more users) or create an issue.

Good idea, maybe I should try this 🙂
