Hi - (BTW, have been a happy paying customer of Taskmator to date, but sync issues are a big problem for me now).
Here is what I observe (just tested).
I have a taskpaper.txt file, stored on Dropbox.
Same file is setup to Sync via TaskMator.
I open and edit file on TaskMator. Call this V1.
I open file, and edit it on desktop. Call this V2.
When I open the file on TaskMator, Taskmator receives / ‘sees’ V2, which is correct.
BUT, V1 is ‘pushed’ to Dropbox, and replaces V2! So now my desktop file is one generation too ‘old’ and the recent edits are lost.
It is as if the files are exchanged / swapped between the devices, rather than the most recently edited version being synced to both.
I do not know if the effect is caused by (for example) leaving TaskMator open on iOS, or other factors.
