Today I was trying to get into my plan, which is for a 2 floors home and, for some reason, every time I try to click on the button to switch from 1st to the 2nd plan, the button disappears.
I´ve always been working using the Chrome browser, but for some reason I can´t switch plans neither create new floors nor basements.
I´ve created my second floor 3 days ago, but I cannot get into that second floor now.
If I click on that button it will disappear.
Is there something I can do?
