AVIF - cannot write EXIF data?

[duittenb]

Team,

First of all: in my quest to "fix my photos" - things like dates/formats/locations/etc XnView has been very valuable, good job!!

When using the AVIF format I noticed that
- JPGs converted to AVIF have GPS and time metadata in the Exif fields
- AVIFs where you edit the metadata Timestamp or GPS will not change.

So it looks like that the "metadata Timestamp or GPS" feature does not support updating AVIF exif data.
Is that a known limitation or a bug?

XnView MP 1.7.2 64-bit (MacOSX) - Libformat 7.180

Thank you!
