Hi,
I am really scratching my head on this one. I am working on my own theme and therefore created a folder + yaml file in the themes directory I already had.
I rebooted everything and now I can’t see a dropdown selection anymore in the system and I am completely stumped. How does one debug this since there is no error message or warning but the dropdown just simply ‘dissapears’?
Thanks already.
Can you post your config for frontend please
This is the code for the frontend. Not really special I think? What I did notice was that the themes are working on all my other machines (phone, other laptop, surface tablet) except for this one (windows pc, chrome browser). Could it be a browser specific thing?
frontend:
themes: !include_dir_merge_named themes
Seems like there are some Browser issues with themes, in firefox (which i use dayli) i can go to Side-menu / profile and “Select Theme” And my current theme is “visible” as u can see in attached pics … in EDGE … there is no such “select theme” … BESIDE it seems to have chosen “Default Theme” by it’s own
Thou, if i go in Edge - upper right corner 3 dots - click (midway) Apps > , then select “install this site as an App” … it’s another Ballgame , It opens with my chosen Theme, And the “Select Theme” is there under “My Profile”
I think i have to crawl to the Cross … just tried on another(my 3rd) Laptop, which also have windows … and EDGE … seems like it was only the “log out - Log in” that did the “trick” … Thou it’s seems actually like a neat “feature” in EDGE ( and apparently Chrome) ( Converting HA into a web-app, it runs in it’s own “safe” environment (own process ) … never to late to learn new 
, thou i properly stick to firefox anyways
