At one point, it even said on the Trello card that it was gonna be fixed in 15.20 or in 15.21, but changed it back to just “Investigating.”
Hey u/Alphasilverhawk. You're correct that the Trello card had the "Fixed in Next Game Update" label recently. The issue was originally thought to be fixed in our upcoming v15.30 update, but after further testing, we were able to reproduce it.
We're actively working to return the Banner menu back to normal and will continue to keep everyone updated on our Trello board.
