If you are switching from one layout to another instead of "side scrolling"on the same layout and you want to have the text box appear in the same spot you can place the UI (text box layer hp all the stuff you normally want to keep) on a separate layer and make it global and just in case paralax 0,0 (in the layer settings).
Also if you have some other kind of setup you may need to just set that text box to "global" on its properties.
I find it better just to make the layer which I'll use as a UI a global to keep it tidy but to each their own. I made a very simple example of the text passing from one layout to the other. (no paralax just the text) Here it is. Just click anywhere it will switch layout and update the text. I hope it helps.
