Make sure you're using supported WhatsApp version (2.18.248)

If WhatsApp does not prompt to restore from LOCAL backup, like below, I suggest to:

  1. disable WhatsApp Google Drive backups from PC (not from phone) - you can enable them back after iPhone messages have been imported
  2. make sure you're using supported WhatsApp version
  3. make sure you uninstalled WhatsApp before using WazzapMigrator
