When beta 11 told me to upgrade to beta 12, the window was so large, the update and cancel buttons were not visible. The window isn’t resizable, so it’s difficult to access them. I assume beta 12 will be the same way when beta 13 is available.
There was an indirect reference to this back in July, and the person was able to view the buttons on a surface by switching to portrait mode. I work on an Acer laptop where switching to portrait mode is more involved. I wanted to be sure you know it’s still happening.
