thank you for bringing this up again. Unfortunately AppConfig is still not supported as the implementation story for our Mobile Client got canceled for the 6.0 release due to timing issues. In the meantime, however, our clients offer an integration for Microsoft Intune which is also documented here: https://community.simplifier.io/doc/current-release/deploy/simplifier-mobile-client/intune/ If you still require AppConfig support, please feel free to request so again via our dedicated feature request portal from here: https://ideas.simplifier.io/
