Range Rover Velar – 10 months ran Multi-SIM well, but now no longer function, secret update

The Range Rover Velar 2018 has been running the Multi-SIM perfectly so far, current traffic information has been transmitted reliably. For one week, the Multi-SIM card has been recognized: “Mobile data” reports: “SIM is not supported” That is, the computer recognizes that a SIM card is plugged in, but the software no longer supports this SIM card used for months. Testing the SIM card in a mobile phone showed that it works as normal as always. So the SIM card is ok. That’s why it is My question is, was a software update from Land Rover/Range Rover unnoticed online that changed SIM-Card functions? Is something known about such software updates? For the time being, it should not be recommended to order an extra data card as recommended by operating instructions. The previous solution worked perfectly.
