10874 and 10875 can't be controlled together after apps updated
my kids use to have both 10874 and 10875 running on the tracks control by two apple devices at the same time before. however, it seems that the two trains are not able to get online together again. i have found that when i want to connect the second train with another device, the first connected train will be disconnected from the first device automatically. i have already tried with all my five different apple devices to connect with the 10874 and 10875. all the results are the same that every connected pair of train and device will be disconnected once another pair is connected. please kindly have a review on this issue and see if you can fix this issue. look forward to seeing the both 10874 and 10875 running on the tracks at the same again very soon.
