Documentation times were taking a long time for them. We had a lot of burnout. And that's not happening anymore as far as providers aren't staying after hours to finish their notes. If they're actually using the mobile product, they're out of their own time, and they love it. When we ask for their feedback, it's always positive.

Open-source forks are no longer maintained by NextGen Healthcare and rely entirely on third-party developers, raising concerns around security, stability, and long-term viability. These forks lack critical enterprise features like the Mirth Command Center, multi-factor authentication (MFA), and the SSL generator, and they offer no official support.
