Remotes falling behind master for sync

[jcross]

Any ideas why at 48 seconds my remotes start lagging behind the master? By the end of the song they are so far out of sync that it is unusable.  I tried rolling back my bbb tune to sign to 7.5 but it still maintains a consistent (but wrong) sync with all the other remotes so it doesn't seem to be an 8.4.1 issue with the remotes.
Screenshot provided with all details.

I ruled out issues with wifi by connecting the tune to sign directly to ethernet and the issue persisted.

If anyone has any ideas I'm open otherwise I will downgrade the master fpp tomorrow to try to get my show running.

Thanks,

Jason

Did you perhaps enable the "Ignore Media Sync Packets" on your remotes?
It looks like they are all off by the same amount, Did you put a media offset on your remotes?

These were all fresh installs which never had "Advanced Mode" enabled.  I verified that Ignore Media Sync Packets was unchecked on all remotes and there is a 0ms offset on all remotes.

It appears I have found the issue...

In xlights I had configured all controllers to start at channel 1 (Keep Channel Numbers unchecked).  Thinking about this more, that was a mistake since my show is run from a pi and not xlights.  Updated all the controllers to use xlights channel numbers and now the remotes seem to be staying in sync... And a few other minor issues have gone away also.

That is great!
