Unfortunately I am unable to edit external PDFs in DTTG 3 using PDF Expert.
I can open the PDF in PDF Expert using the DTTG Files add on, and am able to highlight the document like normal. However, my changes are not recorded in DTTG. In addition, if I close the PDF in PDF expert and try to reload it, my edits are deleted.
Any advice would be appreciated as this workflow worked well in the previous version of DTTG. I am also using the new CloudKit Sync.
