I was told after the End-of-Service announcement it should still work with the mydlink service, but as time goes on and the mydlink backend/agent is updated, old cameras may no longer work. D-Link will not purposely block devices unless there is a sever security issue, but note D-Link will no longer update firmware for the camera.
I still have a 930L camera going after 8+ years sitting in a hot window sill that is still working so I hope it continues to work for a while.
