I thought I would share this experience.
I have three on-line accounts / bank cards at the same institution; that is, 1 for my personal accounts, 1 for my HoldCo accounts and 1 for my OpCo accounts as my financial institution is not setup to have one bank card for three separate entities (at least in Canada).
I setup my accounts to connect to my financial institution via Express Web Connect which worked well for the first few weeks (i.e., automatic update showed all three bank cards and Quicken Mobile account were updating correctly).
Over time the wheels fell off. Quicken went from showing 3 bank cards to 2 bank cards to 1 bank card (i.e., I suppose Quicken does not do well with multiple bank cards from the same financial institution). Quicken Mobile started to show my accounts as needing to be fixed / reconnected to on-line banking. The combined result was that Quicken was not properly updating my bank accounts (because it had lost the bank card information) and Quicken Mobile was no longer a viable method for entering transactions while away from my computer.
The fix was to deactivate all my accounts ties to the 3 bank cards and then re-activate them. This was time consuming given the number of accounts.
The fix was very short lived as within weeks the cycle reoccured with Quicken showing 3 bank cards to 2 bank cards to 1 bank card and Quicken Mobile showing my accounts needed to be fixed.
With that in mind, I went back to the older Web Connect method of connecting my accounts. While I do need to manually / separately download the transactions from my financial institution at least everything is reliable and working. Quicken is properly updating my bank accounts (albeit manually) and Quicken Mobile is again a viable method for entering transactions while away from my computer.
