    First question would be how old was the plant. If you planted it within the last few months, check the basics in this article: https://www.gardeningknowhow.com/ornamental/vines/mandevilla/mandevilla-plant.htm
    If it was an older plant, there is a bacterial disease that can kill them, called southern wilt. You should plant a different plant in its place, because the bacteria remain in the soil. If you want to be sure, you can have the soil tested. Check with the local Extension Service for more information: https://www.gardeningknowhow.com/extension-search/

    Hm-m-m, very interesting. Could be that you have one of those varieties that blooms pale color, and then the blooms gradually turn dark red as they age. So when you bought it, it had all older blooms, not the blooms are new. They might turn color. Another thought is that something the grower used to force growth/bloom for sale affected the color of the flowers, now you are seeing a more natural hue. If you can get the name of the cultivar and/or the grower, you might be able to get more information. Here's an article that has general information about mandevilla: https://www.gardeningknowhow.com/ornamental/vines/mandevilla/mandevilla-plant.htm

    It may be that the one that is getting less sunlight, doesn't need as much water as the other one, and its soil is staying too wet, thus encouraging root diseases. Use a moisture meter or wooden probe to test the amount of moisture in the soil near the bottom of the pot, and cut back on water if the soil seems too wet. It should feel damp, but not drippy or oozy. This article may offer some insights: https://www.gardeningknowhow.com/ornamental/vines/mandevilla/mandevilla-plant.htm

    The mandevilla will have a better chance of making it through the winter if you cut it back, bring it into the house, and treat it as a houseplant. This article has more information: https://www.gardeningknowhow.com/ornamental/vines/mandevilla/growing-mandevilla-indoors.htm

    When you dug up the plant, some of the roots were left behind. Almost impossible to get all the roots when you dig up a plant. A plant has a certain number of roots for each leaf, so your mandevilla is now getting rid of some old leaves, just as you got rid of some of its roots. You can minimize the loss of leaves by acclimating your plant before you bring it indoors. https://www.gardeningknowhow.com/houseplants/hpgen/acclimate-plants-indoors-winter.htm
