Hi ItsMowTime, thanks for posting on the Community
We're not aware of any issues with the Payment feature in QuickBooks Online. To check for any browser issues that may be causing this message, please try signing into QuickBooks through a different browser or private browsing window.
As a workaround, you can manually mark the invoices as paid, with the Undeposited funds account selected in the Deposit to drop-down. Undeposited funds is a default account in QuickBooks Online used for holding customer payments.
Once the payments have been recorded to undeposited funds for each invoice, create a bank deposit to replicate the bulk payment (+ New > Bank deposit > Tick all payments that apply under Select the payments included in this deposit). Once saved, you can then match this to the payment in the bank if you have this connected in QuickBooks.
