Ok I did the jump now I am on 0.84.1 but in frontend I have the below. Not sure what I have to do now: wish to try the new storage method
No config found.
EDIT: had to press F5 on the browser, now I have the frontend back, but not lovelace, my old (from me not updated) legacy UI. On the top right clicking on the three dots there is a menu CONFIG UI, then I clicked TAKE CONTROL OF UI, then RAW CONFIG UI, but it shows nothing. I am a bit confused …
