Hey just wanted yall to know, if you're transitioning form Synapse 3 to 4, make sure to back up all of your chroma profiles, as well as other profiles for the audio, mouse, etc, because the migration of profiles is broken, and will probably only transfer the default profiles because potato. Also your old light effects will most likely not work, or not sync well if you're using the migrated profile.
Im saying all of this because I almost lost all of my profiles and stuff, thankfully I was able to recover them when upgrading from 4 back to 3
