I am currently running KC version 220.127.116.111-0+63.1 on Debian Stretch and tried to upgrade to latest nightly (18.104.22.1684-0+150.1). Unfortunately the upgrade let all my Filter Rules disappear in Web App and non of them was working anymore. After restoring my backup snapshot of the VM running Kopano Core all the Rules were back there again. So it appears that the rules stay in the database* (or are they stored elsewhere?) but aren’t shown and applied anymore. Any suggestions?
* DB is on a different host and hasn’t been restored
