I have received the warnings on both iPad and iPhone, to look for corrupted files in the Ghosts smart group.
Where do I see this please?
EDIT. Found them using (Edit button) Two Ghost folders both empty so I assume I am not affected.
Successfully deleted the Ghost Folders, emptied Trash and turned Syncing back to Automatic.
This morning was the first I have heard about this problem and the GHOST message appeared after installing the latest DTTG version. But I see now it has been well known for three days. I don’t use Twitter.
Do you remember how many and what kind of items this smart group contained?
I added my experience and further info in a post in the main thread about this:
Sorry for double posting.
Bottom line: these two Ghost groups were files not groups and had size zero before first being imported to DEVONthink in 2019. So they have been picked up as Ghosts because they were size zero, but this has not happened as a result of the DTTG 3 problem.
