Before troubleshooting
Open Last Time → Settings → Export complete backup. Do not delete or reinstall the app while the only copy of your history is stored locally.
A record appears to be missing
Open the item and review its complete History and Recently Deleted. If the item is shared, confirm iCloud Drive is enabled and allow pending changes to finish.
A reminder did not arrive
Open Settings and check notification permission and the Scheduled count. iOS controls final delivery timing; Last Time cannot promise medical-grade or absolutely punctual reminders.
Devices are not in sync
Confirm each device uses the same Apple Account with iCloud Drive enabled, then open Last Time on every device. Keep the app installed until all pending iCloud changes finish.
Restore a lifetime purchase
Open Settings → Restore purchase while signed in to the Apple Account that bought Last Time Pro. Restoring never deletes your records.
Prepare a support report
Open Settings → Support → Share support report. The report contains app state needed for troubleshooting and is not sent automatically. Review it before sharing and remove anything you do not want to disclose.
