In the App Settings, add an email address for analysis. All recognized flights will be automatically added to your flight feed.
The IMAP option is for accounts with user domain names or for iCloud. Note: If you want to parse flights from iCloud email, connect it via IMAP instead of the iCloud button.
Go to Settings.
And connect your IMAP/Gmail/Outlook/Apple/Windows Live accounts.
Go to Profile > click the three-dot button in the upper right corner > Settings > click on "Import Flights".
Now you can connect your account.
