On mobile, the buttons for switching tabs appear behind the Developer Console which partially obstructs the view, which can make it harder to switch tabs. This happens on all pages of the Developer Console.
This is shown in the screen-shot provided.
I run the most recent version of Roblox on Mobile and my device is an iPad Mini generation 2.
This bug also occurs when you resize the Console to a smaller variation on Desktop.
(This no longer occurs on Desktop)
