Reloading through the Developer tools → UI Lovelace Minimalist entry (the entry in the documentation seems to be outdated as far as where this setting is) has never worked for me, even after forcing the browser used to access HA to refresh the cache. Only a complete restart of HA works which can get pretty tedious when working on custom cards.
Am I doing something wrong and are others here able to get things to properly refresh without having to restart HA?
edit: Found I had to use “refresh” under the three dots in the top right in the dashboard views, HA seems to have it’s own cache independent of the browser and that one wasn’t getting cleared.
