We are having this same exact issue with our Vive Focus 3. I have tried to install a new batch configuration just like Fabian did, but after the factory reset, the old batch gets reinstalled.
This is likely because the firmware needs to be updated, however, both the headset and the Vive Manager app do not show any new firmware updates. Trying to update via the Vive Business Manager doesn't work either, as it stays stuck at "Waiting..." and doesn't do anything. Our headset is also on version 3.0.999.94.
We have also signed up for the Beta program, but there is no "Beta features" option at all, likely due to the inability to update the firmware.
EDIT: Additionally, factory reset without a batch config file does not work either, as it simply reinstalls the old one.
