Description
The functionality seems ok is the original layer is a PostGIS one, for example.
If it is a WFS-T and the edits made off-line are simple (like just adding a polygon) then the synchronization back seems also ok.
On the other end if edit in the off-line layer are more complex (like moving 1 feature + adding 1 feature + removing 1 feature + 1 editing one feature geometry) then the synchronization seems to produce very bad effects, like data loss (the edited features disappear) and also features duplication (the feature being moved).
The attached video probably is more clear > https://www.dropbox.com/s/ch2zyqefjrzlb2c/Recording%20%231.mp4?dl=0
This was seen on 2.18.9/10 as well 2.14.15/16 using a Geoserver endpoint.

If the above edits operation are done one at a time (then synchronize back, then placing again off-line the datasource) it seems it all goes as expected.

one more note: this does not seems to happen in the endpoint is qgis server, but I have been able to test only with lines, as if the wfs-t/qgis server layer is a polygon when placing this off-line I always gets messages like:
Offline Editing Plugin: ERROR: 246 feature(s) not added - geometry type is not compatible with the current layer.

this has proven to happen only if the underlying datasource has no primary key (i.e. is not a real database). Apparently there is no way to fix this, so a warning has been added.

this is a completely separated issue and a new ticket has been filed.
