Evening,
I was following along to Daniel responsive design blog here last week and it was all working fine, as per the screen shot 
but tonight after i made a change and publish the app to view it, it's not take the full width of the page as it did above
the only thing that changed seems to be the version of Powerapps, in the working version at the top was published with version 3.19044.15 and the one that isn't displaying correctlu is 3.19051.14.
Is anyone else having issues
