I understand this is an ongoing known issue and I need to know if it will be resolved. The setting in Account and Settings/Sales/Custom Transaction Numbers cannot be disabled. I have the WooCommerce Connector from OneSaas (Intuit) to sync orders from WooCommerce. There is a setting to assign a new invoice number to these sales using the existing numbering sequence in QBO. This feature will only work if you turn off Custom Transaction Numbers, which as mentioned cannot be done! I gave up on the invoice number integration and decided to use two unique series of invoice numbers, one for manual invoices and one for WooCommerce orders. The problem now is the invoice numbering sequence in QBO now defaults to the number from the last invoice that was entered. Following each WooCommerce order the numbering sequence changes and I have to close the invoice, go see what the correct invoice number should be, then manually change it to the correct number. I'm new to QBO and don't have a problem switching to something else if there is not a swift resolution for this.
