You are receiving an 'Export failed' message when attempting to export bank statements to SBCA.
Sage Business Cloud Accounting integrated companies.
Typically this issue is caused by an expired token within your integration.
To clear the error, please do the following:
Disconnect the company's integration (this does not remove any bank statement data).
Connect the company to SBCA again and allow a few minutes for your data to sync.
Attempt the bank statement export again.
