Backup
If you want to make a backup of your notes/highlights please copy subfolder "user_annotations" in folder "JW_Helper" (for location of this folder please see app settings - base settings) with a file manager (e.g. Solid Explorer File Manager)
Please install JW_Helper on your new device and copy the backed-up files to same location. You may also copy the other subfolders if you like to keep your downloaded publications as well.
