When I load the root of my domain for HA, the page loads in non love-lace mode and then redirects to lovelace/0. This is actually visible and very annoying. Didn’t have that before.
Didn’t find other people complaining about that on 0.84.
Sorry, Can’t help here. I haven’t upgraded yet. It seems like some major changes happened to make lovelace work faster. I’ve noticed that I have a cached page appear prior to loading the first lovelace page. According to @balloob this should go away when lovelace replaces the old UI fully. Might have to grit this one out for a bit.
