Same here, using Dynamic DNS (Legacy):
"Please make sure to upgrade to os-ddclient before 22.7 is released as this plugin will be removed from our repository"
We use this plugin for years now using the "custom" profile. So that it just calls a specific URL whenever the WAN IP changes. I tried "os-ddclient" but there is no way add a custom URL.
Please add it or leave the old plugin.. it just works.
