With installing DevonThink 3 I have lost all my tags – a job of years.
Where exactly are the tags missing? Just installing the application doesn’t modify any of your existing databases (in case that you used version 2).
I am using DevonThink3 about one month. Yesterday I made some tags in a new document. Today this tags are gone. In older documentns made by DevonThink 2 a lot of tags are missing but not all.
What kind of document did you create and where exactly did you add the tags?
