In the script 'MirrorSync Customization (Master Code)' around line 68 it implies that mutating the $$MIRRORSYNC_USERTOKEN var on the server would in turn affect the spoke device.
Currently I am serializing some params via Let notation from spoke to Hub but I would like to pass back some metadata also. Changing the $$MIRRORSYNC_USERTOKEN var here does not seem to surface on the spoke.
So two questions:
1. Does this $$VAR get passed back to the spoke at all and if so, where can I surface it (what context) ?
2. What are some alternative techniques to pass meta data from Hub to Spoke? ( I am implementing some version control and auto updating and would rather not have to sync another table just to pass metadata )
Cheers!
