Does Lovelace show a different interface for different devices?
After recovery my ipad shows the old interface, on my PC I get a new scrambled version. I’ve deleted my cache and forced a reload on the PC but it still gets loaded with the scrambled version.
Safari on MacOS Catalina uses some kind of cache that is un-clearable through the developer menu. The only way to clear the cache is to go to Safari->Preferences->Privacy->Cookies and website data->Manage Website Data then delete the info stored for the HA ip address.
The interesting part is that both Firefox and Chrome also kept defaulting to the corrupt version until I cleared the cookies/web data in Safari. Now all 3 browsers are working with the correct Lovelace interface.
