I installed DT 3 (without removing the 2.0 office pro version…).
Than I opened in DT 3 my 3 old databases from DT office pro 2. No problem.
BUT: when there is a sync (via dropbox - 1 database) between DT 3 and DTTG,
only the inbox of DTTG will not be synced with the inbox of DT 3.
Files in the database no problem.
On the iPhone I had to move the file from the inbox to my DTTG database-inbox,
then it comes from iPhone to the DT 3 database-inbox.
I think, the DTTG global-Inbox is still connected with the old DT 2 Inbox?
Both inboxes are shown in the finder (….application support…).
In DT 3 its named inbox.dtBase2 22.12.2014/24.10.2019 with the new icon.
In DT office pro 2 also inbox.dtBase2 22.12.2014/22.10.2019 also with the new icon.
(I have to admit, there are digital pieces since DT 1.0)
I have too less knowledge to remove, erease, shake and such things
without knowing, what I do…… Thanks for Help.
