I have the same problem with Caisse Desjardins. It seem that Desjardins changed their settings. 

I tried to re-add my bank accounts, and it works for 2 of them. (the credit card accounts)

But for the operations accounts, it gives always the same account whatever the one I chose... Not my principal account of course.

May be if you try can re-add your account, you'll be be more successful with BMO...

Finally, after one week, I received a communication from Sage about the issue, and now my firsts accounts works again... 

HI HAVE SAME ISSUE WITH ALL MY ACCOUNTS CREDIT AND CHEQUIN, BUT DESPITE SPENDING HOURS ON THE PHONE WITH SAGE TEAM NO RESULT THEY SAY THE PROBLEM IS THE BANK, THE BANK SAY THEY HAVE NO PROBLEM.

WHO IN SAGE DID YOU ADRESS YOUR ISSUE TOO? CAN YOU GIVE ME A NUMBER OR DIDI YOU CALL THE USUAL HELP LINE, WOULD APRECIATE THE HELP

THNAK YOU

I didn't call Sage since they never fix my issues. The communication I received was a general email...

The problem was finally corrected by itself magically. I'm sorry that I can't help you more...

Hi Tanya:

Banks generally work on their own schedules and prepare things when they are ready. I would download the banking file manually and import the file into Sage 50 rather than wait for them.

Thank you i appreciate the feedback

Thank you
