I’d be happy to help, Karen266.
To clarify, when you say "posted" bank transactions, are you referring to transactions that have already been categorized and are in the Posted tab, or are they transactions that have been downloaded from the bank but are still in the Pending tab? Knowing this will help us narrow down the possible cause.
If you’ve already verified this but the transactions still aren’t showing in the Bank register, try logging out of your QuickBooks account, then log back in using an incognito or private browser. This helps rule out issues with your browser’s cache or saved data.
Let me know how this goes. If you have other queries, feel free to ask in the comments section.
