BMW iX..What should I do with app errors? Driving distance drops sharply in the snow

This BMW iX was leased 14 months ago. So far, it has traveled 14,000 miles (about 22,500 kilometers) and has been tested under various conditions. Overall, the performance was satisfactory, but last winter, it was evaluated that the driving stability in the snow was somewhat insufficient.
iX has a dual motor-based four-wheel drive (xDrive50) system, so there was no problem with power allocation, but the existing Good Year tires this season showed less grip than expected on roads covered with snow and sleet.
To improve this, driving tests were conducted after replacing it with Remedy WRG5 tires provided by Nokian.The new tire showed a clear improvement in grip compared to the previous one. Even on snow and ice, the vehicle moved more stably. More predictable steering was possible even in deep snow.
Compared to the experience of using Nochian's winter tires several times, this all-weather tire provided a clear better grip than the existing Goodyear tires this season. In particular, the fact that iX was able to climb a steep driveway without snow was evaluated as a positive factor.

However, it was difficult to expect performance as much as dedicated winter tires such as Hakkapeliitta stud tires or Bridgestone Blizzak and Michelin X-Ice in Nokia.
The new tires have also caused problems with the vehicle continuously displaying some warning messages. Since there is no model that exactly matches the existing 235/60 R20 standard, the tire of the 255/55 R20 standard was installed, and a tire pressure confirmation message was output every time starting from then on.
It is regrettable that the warning does not disappear even though the air pressure is within the normal range.Another problem with the vehicle caused BMW's digital key and app errors. The ability to lock and open the vehicle using the Samsung Galaxy S23 Ultra worked normally, but the vehicle suddenly disappeared from the My BMW app about a month ago.
The digital key itself worked without problems, but it was inconvenient as it became impossible to check vehicle information and use remote air conditioning functions.

The inability to warm up the vehicle remotely, especially in sub-zero weather, was an inconvenient factor. However, a few weeks later, without any action, the vehicle was re-registered in the app and all features began to function normally.
Winter driving efficiency has also decreased. Initially, it recorded a driving range of 3.1 miles (about 4.99 km) per kWh in relatively warm temperatures (4-10 degrees Celsius), outperforming EPA-certified efficiency (2.9 mi/kWh).
The temperature decreased to 2.5 mi/kWh as the temperature fell below 0 degrees Celsius. In the extreme cold wave (-23C), it fell to 2.3mi/kWh. This is about 242 miles (about 390 kilometers) less than EPA-certified driving distance (307 miles).

BMWiX showed strength in terms of practicality. The Christmas tree transport test allowed a 7.5 foot (about 2.3 m) tall tree to be loaded with the trunk closed. The base of the tree was placed between the front seats, wrapped in a blanket to prevent resin contamination, and loaded, and there was enough room to utilize the trunk space.
Through this test, it was confirmed that the BMW iX improved its snow driving performance in winter. However, the limitations of all-weather tires, vehicle software-related issues, and reduced driving distance in winter remain challenges to be solved.
