I am having the same problem. I deleted the T5 (I actually did not receive a T5 this year because the interest earned was too low, so I just inputted the small interest under "earned interest/investment income without a T5". But in my case deleting the T5 did not solve the problem. I still cannot submit the returns. I too was told to wait a couple of days for an update (call 1 to service), and then told that it is CRA's fault and that I simply need to wait until...? (call 2 to service).
