Could we please have the XMP.Subject field back again ?
The XMP subject tag is still being written. No XMP metadata is written. You are using a Pixel 7, we have fixed a problem with the XMP metadata, this depends on the settings in the Pixel 7. Please test the digiKam-8.3.0 pre-release version (AppImage) from here: https://files.kde.org/digikam/ Maik
Read this Bug 478899 or Bug 479780, the Ultra-HDR setting triggered the problem. Maik
I tested it again here with a Pixel 7 image, XMP.dc.subject is written with digiKam-8.3.0. Maik
Dear Maik, THank you so much for your swift responses. I'm glad this is all sorted out already. I verified the fixes with the latest AppImage bundle: digiKam-8.3.0-20240125T080925-x86-64.appimage And all is working back a charm like before.
