Unable to update my Rider 550

My Rider 550 has not got an update since 2019 yet. Even the last map update is from 01/2021 (Europe v1065.10748). The internet connection via WLAN works fine, as I can see online traffic an radar warnings. Unfortunately no updates are available. When ever I go to "Settings --> Updates" it says "Ihr TomTom Rider 550 ist auf dem neuesten Stand".
I do have friends with the sdame device. They have at least a newer map. I do have the "lifetime updates" for the rider. Why it dosen't work? Does anyone have an idea or a solution for this problem? Thx.
