Reactie van Synology: Thank you for contacting Synology Support.
The Symform is the 3rd party application, not developed by use.
Currently with Synology 4.3 released, Symform application is not fully supported on this FW. Our developers are working on some of the issues that are preventing us from supporting this FW. We will soon release a new build for Synology that will fix the issues you are seeing. I will update you on this case once we get this build ready for release.
