I just upgraded to 2.3 and now I cannot edit. Here was my workflow:
1. Create the feature
2. Fill in the attributes
3. I then did a reconcile/post
4. Went back a few minutes later to see that the feature was there, but none of the attributes were saved.
5. I am now trying to update just the attributes, and I cannot.
The created feature seems to still be in my 'version', but when editing attributes I do not get the option to click on the 'Save' button on the edit tab. See screenshot below, with edits shown in red, and the grayed out Save button.
