Thanks for coming back for more support, @swathinanon. 

I can see similar reports about Chase accounts not appearing in the list when connecting. I know we need to fix this quickly, and I assure you that this has been raised to our banking engineers to understand why this unexpected behavior is happening. 

For now, I'd recommend you contact our Customer Care team again so they can add you to the list of affected users of INV-49161. You'll be notified then via email about its progress, so check your emails regularly. 

For future reference, read through this article: Reconcile an account in QuickBooks Online. It helps you learn about reviewing your transactions in QuickBooks to ensure they match your actual bank and credit card statements. 

Feel free to message again if you have additional concerns. We're always happy to attend your needs.
