My conspiracy theory.
After the latest software update, I submitted my taxes (netfile). It rejected twice (capital gains issues). I ended up deleting my T3s and cleared Schedule 3. I re-entered my T3s... submitted and it was accepted! I did my wife's a couple of moments later and it was accepted on the first go (almost identical return, but no capital games).
HOWEVER...
My wife's return was accepted and her status switched to "Assessed" in a matter of seconds.
My return, which was accepted on the 3rd attempt and is stuck in "In Process".
I have a feeling my return has now been flagged for an audit.! The first two attempts must have been different from the third. I feel like they are getting their fine tooth comb out!
