    The 2 reports, in full

    2 Tage später hatte ich plötzlich ohne mein Zutun die Firmware 1.15.21.1 v. 27.05.2026. Geänderte Oberfläche. Nicht zum Besseren. Und meine vielleicht subjektive Verbesserung über die Reichweite des WLAN hatte sich in Luft aufgelöst. Alles wieder beim Alten. Und das erste Mal seit langem wieder ein Andockfehler. Er fuhr wieder aus der Ladeschale heraus. Erst beim 2. Anlauf klappte es.

    2 days later I suddenly had firmware 1.15.21.1 dated 27.05.2026 without any action on my part. Changed interface. Not for the better. And my perhaps subjective improvement in WiFi range had vanished into thin air. Everything back as it was. And for the first time in ages, a docking error again. It drove back out of the charging dock. Only worked on the 2nd attempt.

    It's mowing quite well again though. The new iOS app is annoying now instead. There's always something :-D

    That's everything we have — and the reports are mixed. We'd rather show you 2 real reports than a made-up percentage; if you're on this build, yours is the report that moves it.
