Unlike in B1300 I couldn’t get GL DDNS active on Flint router. It turned it on but I get a message when I run DDNS test saying " Your DDNS is not effective yet. Please try later. Retry"
With this issue I’m not able to set DDNS in nextDNS to auto update IP address, doing it manually every time, especially with Flint WiFi or some other issue it has where router completely stops working.
