Lightroom for iPad doesn't see preset color profiles

Hello, I really need your help! I am a photographer and I always use my iPad for editing. I have a huge problem with color profiles, which are built-in the xmp presets (which I bought). These xmp presets work perfectly on my desktop Lightroom. But they dont work on my iPad. Lightroom for iPad simply doesnt see these built-in color profiles! Even if I convert xmp-s into dng-s with these profiles. They just dont work on iPad. Thats soooo frustrating and sad. Please help! And sorry for my English, its not my native language...
