Got it !!
That is how I thought that it worked.
Thanks

I would delete my Ancestry tree and re-upload if I was a trusting soul. Unfortunately I’m not. While I consider my RM tree to be my master and do nearly all my updating there my Ancestry tree is my oldest, because I started with FTM years ago (before Ancestry). I got annoyed with them at one point and started using MyHeritage, along with their desktop app which was both Mac and Windows compatible (at the time). I never deleted my Ancestry tree, and kept both updated for a time, but started using MyHeritage for my Mom’s and wife’s side, and use Ancestry for my Dad’s side as my sister was doing research there. So Ancestry drops FTM and I get the RM offer. It looks good, and I buy it right away. MyHeritage’s desktop software is abysmal, won’t even let you merge duplicates. (to this day BTW) RM gives me searches on MyHeritage and Ancestry, plus Family Search. So once TreeShare is available I create a new RM database from my Ancestry tree, and I merge my MyHeritage data in and spend months merging duplicates and syncing with Ancestry so I have one tree. That said, if I drag and drop my database into a new one, which I did many times during the RM8 beta, I’ll come up with several hundred differences with my Ancestry tree. From time to time either RM or Ancestry will burp and I’ll get several thousand. I log the counts in a spreadsheet and the number of people in either tree has never matched. I have them down to a few dozen, but until they do I won’t be deleting the Ancestry tree and refreshing it.
I don’t think manually synchronising is just a concept and see nothing wrong with the phrase. Synchronisation does not have to be an automatic process. Think back to those old movies where the undercover agents or villains or whomever said “synchronize watches”. It didn’t happen automatically - they manually adjusted until all matched. Much the same with TreeShare and Ancestry. They will remain synchronized until something changes.
