Can't update UEFI firmware on Lenovo Thinkpad Yoga 14 (20FY) with fwupdmgr - does not apply update after reboot

A couple of days ago Software Manager notifies me about a UEFI firmware update when clicking it, nothing happens.

I reboot and again it notifies me of the same update (apparently it didn't apply). So I try to resort to fwupdmgr and I type in:

~$ sudo fwupdmgr update
Downloading 184.55.3510 for UEFI Device Firmware...
Decompressing… [***************************************]
Authenticating… [***************************************]
Updating UEFI Device Firmware from 176.0.1202 to 184.55.3510… ]
Scheduling… [***************************************]

An update requires a reboot to complete. Restart now? [Y|n]:

So apparently there is a reboot step to update the firmware. I answer 'yes' to reboot. After that the laptop reboots a couple times. The first one seems to execute a bootloader called 'fwupdx64.efi' or something and finds a file under /EFI/ubuntu/fw, seemingly good.

Then after that reboot, the screen goes blank for a moment and the laptop reboots again normally. After loggin in again, the device shows the old firmware version number and the Software Manager again notifies me about the update.

This is the output of the device if I type in fwupdmgr get-devices

First thing I came across is that the firmware is detected as a Thinkpad T460s and mine is a Yoga 14 20FY (I know Lenovo uses almost same hardware on most of it's Thinkpad line) so maybe the update is not for this laptop, but fwupdmgr recognizing it as such seems odd.
