Hi all,
I had a similar problem, although not the same.
I have a site, where some pages are edited with Bricks and some with Classic Editor (and subsequently rendered by Bricks template). My clients were totally confused which pages are made by Bricks and which by WP and which type of editor to use. They kept using the wrong editor and thought the page updates are not working. They also tend to switch the rendering between both editors.
So I made a little JS tweak to switch to Bricks tab in the Classic Editor by default, when the page is made with Bricks. The whole topic is here: Buggy behaviour in Classic Editor view
Maybe it can help someone else with the same problem. Or maybe someone here can come up with a better solution. Nevertheless, I find the current solution in Bricks a bit confusing.
