Settings & backup
Refresh copies this browser’s projects and prints into the shared cloud copy, then downloads that copy back, including new Anycubic prints. The first refresh uploads the list already saved in this browser. Nothing already here is deleted. A snapshot of this browser’s list is kept on the phone first.
JSON is a full backup (projects, photos, notes and print jobs). The CSVs open in any spreadsheet.
Merge backup (JSON) only adds: projects you don't already have (same name, ignoring case) and print jobs you don't already have (same file, printer and start time). Nothing you have is changed or deleted. Restore JSON backup replaces everything with the file.
Throw away all changes and go back to the starting list (your 23 projects and the 74 Photon M7 Pro jobs from your Anycubic Cloud history).
