I use DTTG on my iPad using “iCloud (CloudKit)” sync locations.
My first issue I think is a known “feature”. I index an external folder (located on a cloud server). Basic sync between my Mac and the iPad using DT and DTTG works. I add new files on the Mac to my DT database and those files appear in DTTG - but it takes some time. My problem is connected to the annotations. The sync here is not reliable. Annotating on the Mac will be visible in DTTG most of the time, but the other way around doesn’t do it.
If I add the PDFs to an internal database (I don’t want to do this, but if this is the way to go…) the annotations made on the Mac with DT always appear in DTTG after a short time. But if I use the iPad the sync doesn’t work as I expected. If I open the PDF in DT and mark the text nothing get’s synced. If I enter the edit-mode first and then add some annotations in DTTG - after leaving the edit mode they sync with the Mac (together with the new annotations I made without entering the edit-mode). Is this how it should be? Seems to me that the edit mode flags the file for the sync and without entering the edit mode the new annotations will be ignored.
