The issue appears when in the tab “TOUCH”, which already has Page1, you create a Page2.
But there is not the bug, is in the app: once you run the app and log in correctly, you can see in the bottom your 2 pages… but if you enter in page2, as soon as you press any button or fader or whatever you will return to page1.
The only way to be able to modify your parameters in page2 from the app, is changing the order of the pages in Daslight. Then, voilà… but you cannot enter now in page 1.
