Drag-n-drop not working

[Zabazabazaba]

Hello. 
I almost bought tests for the CCNA, but I found that in questions with drag-n-drop answers I can’t drag at all. It is an iPad. Browsers: Chrome, Firefox, Safari. All the most recent versions. 
Please help. 

Thank you for your attention. 

Ivan Zabaluyev.
