I recently got a new iPhone and DTTG has not been working on it properly since the new phone was set up. I separately run DTTG on the iPad and it works perfectly. The files are synced using Devonthink 3 over icloud.
On DTTG on the iPhone, when selecting settings>locations>iCloud, all that shows is Global Inbox, and none of my databases. And even if I try and synchronise Global Inbox, I get an error log that says that “can’t create folder of database “global inbox”, path exists already”.
Following a tip in another thread, on my Mac I went into the iCloud settings to delete the devonthink data in iCloud. Thereafter Devonthink freshly uploaded all databases to iCloud.
As I mentioned previously, DTTG working perfectly on the iPad.
