Dviewcam mobile not working with DCS-100 after update?

Question

CCTV

It's even more of a cry from the heart! We took video equipment from D-Link for testing, everything was checked, purchased, launched at several sites, everything even worked for almost a year and one day the Dviewcam mobile update arrives in Apstore and Google Play, there is no more support for DCS-100, only support remains the commercial version of the DCS-210 (I never found a price for it), I don’t understand what to do now, can you advise something?
PS. D-Link, of course, acted meanly, I hope that support will be returned in the next versions, otherwise I will stop using their equipment completely, the routers hang, and video surveillance also let us down.
