Power BI Custom Visual Synching across multiple pages

Hey AngeloCustomVis ,

+1, Facing a similar issue with my custom visual.

( In capabilities.json i have enabled the supportsSynchronizingFilterState and set it to true.

I have also set up persistentstate so that it keeps the values when moved off the page then returned you can see what has been input.

I see the visual in my sync pane.  But it does not sync across to other pages where syncing is enabled. )

I am able to do cross page filter but i am not able to update/sync the Visual UI across the pages, it remains in the previous persistent state of that page instead of updating to the latest one. 
Also not able to implement basic Copy-paste to my visual, while using the sync pane i am able to replicate it but other than that i am not able to copy- paste it. 

Please let me know if you have solved the problem,
Any help and suggestions are very much appreciated.
