@Costa I'm sorry that you are feeling frustrated by the app's lack of VPN support. Unfortunately, VPNs haven't ever been fully supported, even in OS 2. However, if you can setup a VPN to forward multicast packets, then SDDP should work and allow the app to find Director. We haven't intentionally done anything to take away or block VPNs, it's mainly that VPNs aren't compatible with how the apps discover Director.
I discourage using 4Sight or a VPN for support. Instead, I encourage dealers to use Composer Pro and a remote monitoring tool (e.g. OvrC).
Personally, I find a lot of value in having a 4Sight subscription that allows me to receive push notifications, answer my door with Intercom Anywhere, and monitor my home remotely (not to mention Alexa or Google voice). But that's me and I am biased.

RE: evaluating bringing back the manual IP address setting. I can't comment on when or if it will be brought back. At the time of my original post we were looking into bringing it back for other, not vpn, related reasons.
