I second the UI frustration, having wondered where the flip the handles had gone – they’re mentioned in the vid tutorial which I’m following to try to wrangle 2020 into one of those designs it’s supposed to be able to make. I’m not against the block editor move, but it feels like I’m wrestling with an octopus in jelly. I understand why some designers have gone old skool with ClassicPress, not a route I’d follow as I like to stick with the main path.
Anyway, I’m glad I found this thread, though I had to sherlock somewhat over a half hour, as it’s removed my frustration.
