4.0.9.2244, can’t find sonarr 4 from synocommunity on my Synology

There is no sonarr 4 it is just sonarr.

Sonarr does not provide support nor maintain the synology packages and you should contact the synology community for further support. Most likely it’s just an uninstall/reinstall without data purging.
