Hi @TheTaxSmith
So I just tried the following
Removed the T4A
Removed the T2125P
Saved, exited, and logged out
Opened again and completed the T4A and the T2125
Once I finish the T4A I get the warning that I must also complete the T2125
Once I finish the T2125 the warning goes away
But as soon as I click "Review" the warning returns and it says I'm ineligible to Netfile. This seems to be the same problem others are experiencing. Any next steps you would suggest at this point?
