After updating to the December release, QSON import seems to have stopped working. I successfully exported an operation to QSON on my iPhone. However, when I imported it on my iPad, a new operation was created, and then the app crashed. Upon restarting the app, I could only see an empty operation.
I’ll have to look into this. There have been many changes around how the internal database is updated, and to be fair, I never tested the QSON Import feature.
