Almost always the cycle start date. Kairos aligns your rotation to the day you told it the cycle began, so if that date is off by one, every day in the pattern is off by one.

Open Setup, find a day you know for certain you were working, and set the cycle start so the pattern lands on it. If the problem only appears around a clock change, make sure you are on version 2.1 or later — that release fixed a daylight-saving bug that could shift a day.

Set Workplace Timezone in Setup, added in version 2.1. It pins your schedule and countdowns to the timezone your job is in, so flying somewhere else does not shift your shifts.

Check three things. First, the code is six characters and deliberately avoids ambiguous letters and digits — no letter O, no zero, no capital I, no one. If someone read it out, a mistaken O/0 is the usual culprit.

Second, confirm the code has not been revoked on the sharing side. Third, make sure the person entering it is on a recent version of the app.

Open the app once so it can refresh, then check that Background App Refresh is on for Kairos in iOS Settings. If a widget is pointed at a shared schedule, it also needs that schedule to still be shared with you. Removing and re-adding the widget forces a fresh configuration.

Because Kairos has no accounts, there is nothing to log back into. Recovery works one of two ways: if iCloud sync was on, signing into the same Apple ID restores your data from your own private iCloud database. Otherwise, use the AES-256 encrypted recovery key you generated. If you have neither, we cannot recover it for you — we never had a copy.
