I cannot see transactions in the iOS app. It shows me there are new transactions but I can’t select the bank account to see and categorize them. Web browser works though.

I'll share some troubleshooting steps to help you view the new transactions, thompsonkr.

Before doing so, make sure to change the data connection on your device.

• If connected to Wifi, turn it off and use cellular data.
• If connected to cellular data, connect to Wifi.

Then, we can try to clear the app's data.

For Android:

1. From More Options ⋮, tap Settings.
2. Select Refresh Data, and then choose Yes.

For iOS:

1. From the Menu ☰, select Help & Feedback.
2. Tap Refresh Data, and then select Refresh.

Once done, restart your device and open the QuickBooks app. Check to see if you have the new transactions. Otherwise, uninstall and reinstall the app.

I'm adding this article for reference: Troubleshooting Quick-Start Guide for the QuickBooks Online app.

Please let me know how it goes. I'm just a post away to help you out until a solution is found. Thanks
