P: Pixel 10 C2PA not handled correctly

Attached is a photo I took this afternoon witih my new Pixel 10.  The various C2PA verifiers and inspectors are happy with it. I pull it into LrC (via the Android Lr app) and try to export it with C2PA attachment enabled. It refuses to do this, simply saying "Couldn't apply Content Credentials (1) and then the file name.

In Ps however I can open it, enable Content Credentials and then export. c2patool likes it, but the online c2pa verifiers/inspectors report breakage and failure to validate.
