This has been an ongoing problem for over 18 months now.  

Agreed my clients are not always available during the work day to deal with banking issues.  They have tried getting new bank card but are unable to then check their banking from their phone only the computer.  That isn't a viable solution to most on the go business owners in 2023.

Do better Quickbooks.  Fix this issue.  Maybe talk directly to Scotiaconnect, as this isn't an issue with ATB, RBC or BMO.
