Hi handymanharvey,

Thanks for reaching out here.  It's important that you're able to update your transactions seamlessly to keep your books accurate and up to date.  QuickBooks Online provides the compatibility you need to get connected with your financial institution and reconcile your account with confidence.  I'll be happy to provide more insight here!

Based on the information you've provided, the QuickBooks app does have some product limitations.  For uploading banking transactions it's recommended to login from a web browser to ensure a positive outcome. I'd also recommend clearing cache to improve the performance and loading time.

Please feel free to contact us if you continue to experience the unexpected behavior.  This will allow us to work with you independently and look further into this from our end.
