lightroom mobile applies setting that i didn’t decide

hi, I import photos from the Nikon Z8 to Lightroom Classic on the laptop. I work on them, select them and keep them synchronized with the cloud. For less than a month, when I look at them from my iphone on Lightroom mobile, adjustments are applied after a second when I open them. (in my case the contrast was greatly reduced and the blacks lightened). I don't understand why there is this automatic setting that is applied.
