obviously there is a problem with the 2 way sync and mike doesn't want to clarify what is possible and what is not possible so how to work with it.
then he deliberatly answers vague answers, trying to brush things under a carpet with wrong copy and pastes and pretending not to understand my request. 
What a dissapointment, i don't mind it doesn't work but the way my request for help has been dealt wih is below par.

I'm not sure how this cannot be more clear: "If you have two separate songs, there is no way to merge the annotations from the two". I understand that this does not work well for you with your setup - there's not much I can do about that at the moment. I have also clarified both here and elsewhere on the forum that the two-way sync can't handle deletions of things in the library due to the lack of a history of deleted objects in the database. There is no way I can magically make that work without that information. This is a lot more complicated than a basic file-based sync - I'm effectively merging databases from multiple devices and have to handle many different scenarios, and some things the database just wasn't originally set up to handle cleanly (i.e. merging annotations from two different users in the same song under the same layer without causing a complete mess of things). 

Saying that my answer was vague, or that I would pretend not to understand your request - that is both hostile and untrue. I always do my best to help people and explain what the app is currently designed to do. Saying that I copied and pasted answers? Nothing could be further from the truth, and it takes me a considerable amount of time to respond to every person individually about their questions, requests and problems. I'm sorry that you don't feel I helped you sufficiently. There's always lots of different ways to go about solving problems with the tools that are available. I was suggesting that only making changes on one device at a time in between synchronizations would be the cleanest and easiest approach. You could also set up completely independent libraries for you and your wife and sync those separately (Settings->Library Settings->Switch Library). Having multiple versions of songs is also an option, and you both annotate those separately. I still think if you want to use the two-way sync though, you are going to run into issues with deleted objects, so maybe using the sync feature isn't the best for your setup. You can also share things using .msf files (https://youtu.be/9quzb3a-djU).

Geoff - thank you, I appreciate it.
