I read and re-read all these different solutions several times and also tried them all.
Finally it was julester23's solution which worked. I had to read it several times times though to understand it.
This is what I did and what you can try to see if it works for you:
Go to your ipad Notes ---> Accounts ---->icloud. You will get a list of documents stored there. Now tap on the right side of the ipad so that this list of documents is not seen anymore but only your latest note is visible. Now click on the new note icon and write your note. This note should appear on your pc, as it did mine.
There are 4-5 folders in the icloud Notes section - All Notes, Gmail, Yahoo, icloud or more if you have added more email accounts. If you write a new note while you are in any other section except icloud they will not sync to your other devices. This is what I discovered after one year of using the ipad. For the past year I never had any problem with syncing the notes to the pc and I have no idea which folder I was using. As far as I knew I was using the All Notes folder, but I am not sure.
Anyway, thanks julester23! 🙂
