Hello Benood,
Thanks for joining the thread - do you see an error message or code during the update?
Only bank accounts with a live connection will show on the Banking screen however you can CSV import transactions in by going to the Cog Wheel > Import Data > Import bank data.
You will be given the option to select the bank account during import and once imported to QuickBooks these will display in the For-Review tab on the Banking page where you can review as usual.
Thanks
