I have a Lightroom Mobile Premium subscription for using it on my iPad Pro 2018. I don't have access to the desktop apps within my subscription and therefore cannot sync my XMP presets over to my iPad using the desktop app. Any suggestions?
I think your only option is to get the Preset 'baked' into a DNG file, Import that and Create Preset from there.
That sounds promising.. How exactly can I convert an XMP to DNG?
I think you'd need Lightroom Classic.
I assume that you maybe have anyway, hence you having XMP Presets, or were they purchased?
Is that really the only way? Yes, they were purchased.
How about trying this, don't have any knowledge of it, but seemed to work-ish for me
I don't if this will work with one of your supplied XMPs, but worth a go?
