Problems with synchronisation

[Bartor]

I have been using MMEX on an android tablet, windows 10 PC and laptop very happily for several months.  Recently however, it has started playing up.
Whenever I sync the database on the android tablet I get an error saying "item does not exist".  And when I access the database via the windows machine, t doesn't pick up any of the recent transactions I have entered.

I have checked and there is only one database in the file location, and as I say allwas working a short while ago but suddenly stopped.

Any help would be greatly appreciated.

As an update, I have been using one drive.   The 2 windows devices seem to sync between themselves okay, but the android device won't sync any changes to the cloud database.  Everything I try to sync I get error, item does not exist.

I use Dropbox to store my db, but having had the same prob as you (1 windows and 1 android) several times , I have given up using Android version for the moment.

I wonder if there is a locking problem somewhere?

Am I missing something but where are the sync settings?
