If you go to manage and then folders you’ll have the option to change the folder style! You could also go to your settings and click on the folders tab. Once you’re able to manage your folders click on the folders you want to change and the option should be available. After that you’ll want to change all the folders in question to the flattened style and they should compress. Both my parent folder and the folders inside them are all changed to this style, and it won’t work otherwise. If there’s anything else I need to clarify please feel free to say so! Hope it helped some ;;
