Inaccurate display of storage usage in Files app after upgrade to 12.0.1

Nextcloud version: 12.0.1
Operating system and version: Raspian
Apache or nginx version (eg, Apache 2.4.25):
PHP version: 7.0.15-1
Is this the first time you’ve seen this error?: yes

Can you reliably replicate it? (If so, please outline steps): The problem is persistent

The issue you are facing:

I’ve upgraded from Nextcloud 11 to 12.0.1 using the web updater, since then the Files app shows inaccurate storage statistics (I’m using around 80gb, it shows about 700mb).
I’ve tried to rescan the files using “occ” (occ files:scan --all), but it didn’t change anything.

This is still an issue, do you have any suggestions? Surely there’s just a database entry to reset?

is it a double of this one --> Wrong capacity display ?

Yes it is, and it’s fixed with the latest update
