Hello @jorisb
Thank you so much for getting in touch.
This is a known issue to us and we are already working on this issue. This will be resolved in our upcoming update.
At present you can navigate to pages> then open your desired page or post in bricks builder in a new tab.
But we will bring a solution soon.
Thank you for your concern.
This is still not resolved, the opening in new tab opens the iframe in WP admin as well. I really like Adminify, great job on dragging WP UI from the 19th century! But this makes me stay with basic WP UI as I build everything in Bricks. Would be awesome if it got resolved. 🙂
