Bug Description

Error message received:
calibre, version 6.9.0
WARNING: Failed: Kobo database version unsupported - See details

Your Kobo is running an updated firmware/database version. As calibre does not know about this updated firmware, database editing is disabled, to prevent corruption. You can still send books to your Kobo with calibre, but deleting books and managing collections is disabled. If you are willing to experiment and know how to reset your Kobo to Factory defaults, you can override this check by right clicking the device icon in calibre and selecting "Configure this device" and then the "Attempt to support newer firmware" option. Doing so may require you to perform a Factory reset of your Kobo.

Discussion of any new Kobo firmware can be found in the Kobo forum at MobileRead. This is at

Device database version: 171.
Device firmware version: 4.35.20400

Windows 10 Pro PC
Calibre 6.9.0 (Confirmed fully updated)
Kobo Aura H2O Edition 2

Confirmed there is no recent reports of this already. Creating bug report so there is notification of the updated driver. Had the update while doing a sync to get new books from Kobo.
If you need further logs, please let me know where to get them from and I will attach them.
