Hey thanks for that feedback Dan, I was getting a complex that i was the only one!
I have decided meantime to use my online Ancestry tree as pristine and only do updates there. I back it up after major updates and once a month which ever is first. I then import it to FTM 2 and use it only for reporting which i think is great. I also have a windows version of FTM that i run on my laptop that is how i have been using FTM for more than 12 months on windows merely as a reporting tool, also great for when i am travelling and visiting rellies I can then share easy.
I have not had very good response from Ancestry customer support; it is as if they follow a script and the support people seem to infere that the issues are user related rather than SW related which is a pity, we need a few more people reporting the same problem to get recognition. When the program is syncing OK it is great.
I did have some issue with corrupt data it was mainly date formats when accepting hints, and also problems with duplicates but have found just doing the updates in one system seems to work better.
