Troubleshooting
Fixes for the common problems. Sync that stalls, reminders that do not arrive, habits that do not tick, a missing purchase.
Most problems have a quick fix. Start here.
A device does not show my latest changes
See iCloud sync. In short: close ThisDay from the app switcher and open it again; if that does not do it, use Rebuild from iCloud under the iCloud row in Settings.
Reminders do not arrive
Check that notifications are allowed for ThisDay in the iOS Settings app, that the item has a time and not only a day, and that no Focus is holding them. More in Reminders and notifications.
A Health habit does not tick
Open the Health app, go to Sharing, Apps, ThisDay, and check that it may read what the habit follows. Health data can arrive late from a watch; ticking by hand always works.
My calendar is missing
Check Settings, Calendars in ThisDay and choose the calendar there. If it is not listed, add the account to the device first. More in Calendars and Apple Reminders.
SiriAI or Auto sort is missing
Both need Apple Intelligence: iOS 26 or later on a device that has it, turned on in the iOS Settings app, in a language it speaks. More in SiriAI.
My purchase is gone
Open the ThisDay Pro screen in Settings and tap Restore purchase, signed in to the Apple Account you bought it with. See Free, Pro and purchases.
A widget is out of date
Open ThisDay once. That asks every widget to draw again.
Still stuck?
