My HEIC imiges from my Samsung 22 ultra will open but are painfully slow and have been told by support its not supported. As its getting on been looking at a iPhone 16 Pro Max but unclear what support PL9 actually give its HEIC ether. Has anyone used PL9 with a more recent Apple phone with HEIC
Yes.

Support for Apple ProRAW and HEIF/HEIC Image Formats
PhotoLab 9 offers full compatibility with Apple ProRAW and HEIF/HEIC.
• ProRAW images from iPhones can now be opened and processed, with built-in tone mapping enabled by default.
• HEIF/HEIC image formats are now fully supported.
Thanks when I looked up what was suported only the old Apple phones are still listed
This depends on what is meant and understood as “fully supported”. The PL9 user manual states that both HEIC and ProRaw files can be exported as linear DNGs. Not at present, however, and I have reported that to DxO. So far, no response. Export now is to JPEG or TIFF only, not HEIC, JPEG XL, or linear DNG.
