How do I view more than 300 items on a page in the bank register? QB Desktop allowed you to continuously scroll. QBO requires me to click "Next" for the 18,771 pages

You've come to the right place for assistance, tim.lambert. I can help you view 300 items on each page when reviewing transactions from your bank registers.

You may modify the Row dropdown section from the banking registers of your file to enable 300 items to show on each page. To help you do this:

1. In your QuickBooks Online account, go to Transactions and select Chart of Accounts. 
2. Find and choose a specific bank. Then, click on View registers from the Action column.
3. From the bank registers, click on the Gear icon and select 300 under the Row dropdown.
4. Wait for the page to refresh.

Moreover, I'm sharing this reference to help you review and reconcile your accounts, so your books always stay accurate: Reconcile accounts in QuickBooks Online.
