How do I undo an import?

Right after the import, on the same screen, tap Undo this import. Veilleuse shows Import undone: nothing from that file is left. The entries you logged yourself are not touched.

If you see The import could not be undone. Check your connection and try again., check your internet and tap Undo this import again.

The undo button is only on that screen. If you already closed it, ask us.
