Yes, I have other files -- for other trees.
I checked File --> Open Recent and there were 3 files listed: my primary file and two files for other trees.
I've suspected the issue for about two weeks. However, it was obvious that some 'signal' is getting lost since I could verify that the individuals I worked on Monday night were back on the list Tuesday night. I was not home during the day on Tuesday and did not work with any individuals in RM that day.
I'm also noticing a lot of individuals in my TreeShare list whom I haven't worked with recently. When I first uploaded my tree, I would have clicked the 'Mark as Not Changed' Icon for many of these people. They weren't showing up in my TreeShare list until about 2 weeks ago. Since then, I've been trying to work my way thru the list -- but the list didn't seem to get smaller. When I observed the issue on Tuesday with the THOMPSON surname, I knew something was amiss.
I have "Only show changed people" selected -- but it appears to be pulling a lot of individuals that it shouldn't. It also isn't picking everyone.
For example, I'm looking at TreeShare for Martha Ann Woody in my tree. Everything is shaded green with no apparent differences and no selection boxes. However, she is on my list -- even with "only show changed people" checked.
The list does not seem to change if I unclick "Only show changed people."
Is it possible that something changed on the Ancestry side?
