I assume the ask permission flow should send the request to the parent via iMessage. That is what was shown in the WWDC video for PermissionKit. And I am using the code from the WWDC video and running on IOS 26.2 RC by the way.

For CommunicationTopic, the console shows > several XPC-related errors, and I’m not sure > which of them are relevant. Both of them show an alert view of "Can't ask, An unknown error occurred" I am also having the same error when attempting to get parental permission using a Communication topic (Unable to ask / unknown error occurred). I also am not in Texas if it matters.
