Hi Nitramc, thank you for asking this question. Firstly, self-hosted Journey Cloud Sync has not yet been released for public testing. We plan to release it within the next two weeks. Our technical team is currently ensuring compatibility with our mobile and desktop apps. Additionally, we are fine-tuning the setup steps. As spoken to you in the help desk chat, as long as a Synology NAS can run Docker Compose, the self-hosted Journey Cloud Sync should work. If I have more details, I'll keep you posted in this forum. Thanks! 🙂
