Owncloud update - blank page when opening files

Hi everyone,

Facing the following issue: after licensing extension and updates of our owncloud fileserver.

Users now reported the issue that when they try to open any xlsx files, they get presented with a new owncloud tab, but content is blank

This is reproduceable, even form the admin console we have the same behaviour.

is there a known bug to this or a simple setting that stop the preview edit option?

Let me know what logs could help if this needs analysis trying to search for hints from the owncloud.log file but no luck.

Any help is much appreciated, thanks
