Same issue been biting me. Been editing photos in Thailand 80+ degrees on iPhone XS. Lightroom causes the display to dim as soon as I change color temperature (no pun intended). I have to reboot phone or let it sit a while. Also seems to be draining battery when open in the BG. If I look at iOS brightness prefs they are still fully bright.., LR is taking it over, and what sucks is it is dimming the image, not the display... if I post to Instagram it's dim. Incredibly frustrating.
