I'm not good at making web videos, but I'm sharing anyway because I wanted to demonstrate what happened after my last synchronization. Data is being changed that shouldn't be. Other users need to be aware this is happening. Video is about two minutes long.
1. TreeSync changed data on Ancestry.com that wasn't changed in FTM (new facts became preferred facts)
2. FTM falsely reports that trees are in-sync (they're not!!!)
PS. Who knows what else doesn't sync right. If you use TreeSync, beware!
