# Troubleshoot Planner

## Planner does not open

Confirm that the installed build matches your operating system, then restart the app. If the issue continues, note the operating-system version and the Planner version.

## Sync appears delayed

Confirm the device is online, keep Planner open briefly, and check the item on the originating device. Avoid recreating the same item until synchronization has had time to finish.

## Connected data is missing

Confirm the connected account is still available through its original provider. Planner keeps connected credentials in operating-system secure storage, so an account or keychain change may require reconnecting.
