We are aware of an issue on iOS 27 that can cause Informant to close unexpectedly when adding, changing, or removing a day color. This issue is occurring due to changes introduced with the iOS 27 upgrade.

Our development team has already worked on resolving it, and a fix is currently being tested in our beta version. We are working to make the fix available in a public update as soon as possible.

We apologize for the inconvenience this may cause and sincerely appreciate your patience and understanding while we work to resolve it.
