After Communication Site upgrade of the root site full-width sections are limited
If you upgrade root site's team site template with a communication site template, the new home page (front page) contains one section that can have a full-width web part and it's the first section (uppermost). You cannot add a full-width section down on the page because it's not available in Add Section menu. Is there a possibility somehow to allow full-width sections also on other slots on the new homepage? The upgrade was done with Powershell: Enable-SPOComm... and it was otherwise successful.
