Thanks for reaching out to us here in the Community, @Anonymous.
I'm here to provide some update about the issue with Chase Bank not importing all transactions in QuickBooks Online (QBO).
This has been reported as an ongoing with an investigation number 23738 (or INV-23738). Our Product Engineers are now working to get things back to normal as soon as possible.
While we don't have a firm timeline for when this will be resolved, I'd suggest contacting our Phone Support team and provide the investigation number above. They have the tools that can check your account and add your company details to the list of affected users. You'll receive an email notification once an update is available.
To reach them, you may visit this link and proceed to Connect with a QuickBooks Expert: Get help with QuickBooks Online. I'll also get back to you on this post once I get a notification that the issue is resolved.
Thanks for your understanding and patience while we look into this. Please know that I'm only a post away should you have any follow-up questions. Take care always!
