Linked IP does not update by DDNS (A month-old issue)

Looks like there have been 3 posts about it already in the past month, with many people in the comments confirming that they experience the issue as well:

DDNS not updating every minute

DDNS to NextDNS

Linked IP not updated by the DDNS

The DDNS contains the correct IP, but NextDNS doesn't request the updated IP every minute (only once at the moment of setting the DDNS).

Hopefully the NextDNS team will be able to resolve the issue soon.
