Hello! I understand that after updating the CA DMV Wallet app, it gets stuck on the "startup completed" message. Let's see if we can resolve this together.

First, I’d like to clarify a couple of things:
1. Have you tried closing the app completely and then reopening it?
2. Do you see any error messages, or does it just freeze on that screen?

If you've already tried reopening the app, here are some steps we can take:

### Step 1: Clear App Cache
1. Go to the settings on your device.
2. Look for "Apps" or "Applications."
3. Find and select "CA DMV Wallet."
4. Tap on "Storage," and then select "Clear Cache."

### Step 2: Restart Your Device
Sometimes a simple restart can resolve issues. Just turn off your device, wait a few seconds, and then turn it back on.

### Step 3: Reinstall the App
If the above steps don’t work, try uninstalling and reinstalling the app:
1. Go to "Settings" > "Apps" > "CA DMV Wallet."
2. Tap on "Uninstall."
3. Once uninstalled, head to your app store and download it again.

### Step 4: Update Your Operating System
Make sure your Windows 10 is up to date. Sometimes, app performance can be affected by outdated software.

If after these steps the app still gets stuck, there may be a temporary issue with the app itself.
