@Harm Horstman I don't think the back button functionality works just yet. But I understood it's on the radar of the U-GUi. 

Hi @Mark Jongeling could you give an update on this? Is there a workaround for this?  

Hello Harm, all the opened screens should be available behind the menu button on the top left. You should be able to navigate back to the previous screen this way. Right now the URL is not updated if a screen is opened with a detail tile, so using the back button doesn’t work. This is something we have on our backlog to fix, but currently I can’t give an estimate as to when we will be able to implement this yet.

Hi Peter,

Thanks for your response, in the meantime I have tried to solve it with a ‘Back’ task and process flow with a ‘Activate Form’ action, but this doesn’t work either.

As far as I can see, using Detail Tiles in the Universal GUI is useless, right?

I hope the development team can soon deliver a proper solution for this.
