In version 11 we use to update the layouts by using:
Go to the specific page;
Use button design page;
Define the new design;
Save as Global;
Go to menu administration - pages;
Select the page we updated;
Select the variant GLOBAL;
Go to administration mobile applications;
select the specific mobile application;
select update version and save it;
Thereafter in version 11 this would update the mobile application, now in version 12 it is only updating for the same computer/browser/user, if we change browser, computer or user the page layout is lost. If we keep the same browser and user in the same computer the page layout is kept the same.
Any guess for version 12??
