Share Files Between Devices

Update: Since v3.2 NotePlan syncs also file attachments inside notes between devices.

NotePlan currently only synchronizes images you add to your notes between your devices, but files, such as PDFs are kept locally and are not synced. You can still sync documents and other files using third-party apps and link them into NotePlan.
