Apologies for the late reply.
My issue was not solved by any of the responses here. I had initially tried to change the U.I appearance via the option at the bottom, however, pressing the button simply opened the animation- the same issue I pointed out in the OP.
The solution to this was to (on iPhone) hold the button until I was given the option to open it in another tab. From there I could select the static U.I. by again holding the option and opening in another tab.
