How do I sync my icons on multiple devices?
If you want to use the same icon library on two devices, you can select, as library location, a Dropbox/Box/OneDrive/Google Drive/Nutstore folder.
You can change your library location in the app settings (Account > Settings or press ⌘, on Mac or Ctrl, on Windows).
If you have already some projects on one device, make sure to set the new library location on this device first.
If you select a cloud folder to store your library, don't use the app at the same time on multiple devices and don't share the library with other users. If you do, you may cause a database conflict and the icons will disappear.
