No account images after upgrading

Hello!
I solved it, /opt/mattermost/data was not used at all it seems.
Instead it used /opt/mattermost/bin/data for storing images.
And indeed the permissions was broken for most of the directories in the mattermost folder, probably by the upgrade as you mentioned.
I redid: sudo chown -R mattermost:mattermost /opt/mattermost
and now it works again, thank you
