This is exactly what happened to us. My Netfile submission went perfect. My wife's got rejected. I checked the Netfile code and thought it was wrong so I tried it again but no diff. We contacted CRA to get her account unlocked and received a code my mail so she can get into her account. But no diff for Netfiling, still locked. Then I tried to use Ufile online suspecting that the lock was on the Ufile (Windows) end. I found out I had omitted special Netfile questions that only need to be filled out by the spouse. I was a bit annoyed that Ufile had not warned me about that the first time I tried to file. Anyway long story short: no difference, my wife is still locked out!! Yesterday we tried to contact the CRA and were on hold for little over 3 hours. This was not so bad because the CRA website had warned us about a wait of 3h. The bad part was that after 3h we got a message that due to a technical error they could not connect us and hung up.
Oh yeah, today I got a notice that my 2020 return has been assessed.
