After resetting your data, you need to re-enter your Opayo credentials.
If you issued any invoices with the Pay Now button before resetting your data, your customers can still pay you through Opayo.
Even though your customers can still pay you, it won't mark your invoice as paid. Manually record them once they appear in your Opayo account.
If you have Opayo eCommerce account, any eCommerce transactions downloaded before resetting your data no longer appear. These transactions still appear in your Opayo account.
