I think everybody who is trying to work on a #SynthV1 project in #SynthV2 need to make sure they read up on Dreamtonics' migration guide:
https://svdocs.dreamtonics.com/en/synthv/upgrade/migration-guide
Eclipsed Sounds also has a great primer on Youtube:

I think many complaints stem from people working on SV1 projects not really understanding how things have changed in SV2.
