Hello everyone, four months ago I bought a 2021 Seat Leon Sportstourer. The infotainment system still runs 1803 software. A month ago, the car attempted to download and install a MOI3_EU_SE_R9890L OTA update. The file size is 5620 MB, and after downloading exactly 5114 MB (which takes several hours), the download freezes, and the system says it failed to update. This has happened four times so far. I tried to connect the car to Wi-Fi, but it seems the download continues via eSIM anyway. Has anyone faced such an issue? Is it a problem with the car, or is it something on the Seat servers? Can I do anything to get this OTA update, or can I only install it manually from a USB stick?
