As a RouterOS long-term version user I have problems with DNS timeouts and now complete DDNS service shutdown. It is time to look for alternatives, so we can use long-term version with dynamic IP addresses.

Please post here any *working* solution that you use as an alternative to builtin IP Cloud.

It was only temporary downtime, not full shut down. The current version is quite stable also.
You can script the router to pull WAN ip from your interface if you really need it to on net watch up but that is very long way around an easily solvable problem.
