Hi there! I understand you're having trouble logging into Paychex Flex. It sounds like you've been entering your 5-digit code but are being redirected back to the login screen. I’m here to help you sort this out.

Could you please provide me with a bit more information? For instance, did this issue start occurring recently, or have you been facing it for some time? Also, are you using any specific browser or extensions that might impact the login process?

Let’s try a few steps while I gather more details from you:

1. Clear Your Browser Cache: Sometimes, cached data can cause issues. To do this on your Mac:
- Open Safari or your preferred browser.
- Click on "Safari" in the top menu, then select "Clear History."
- Make sure "All History" is selected, then click "Clear History."

2. Disable Browser Extensions: Some extensions can interfere with the site. If you're using Safari:
- Go to Safari > Preferences > Extensions.
- Disable any active extensions and try logging in again.

3. Try Incognito or Private Browsing Mode: This mode can help rule out issues caused by your cache and cookies. Open a new private window and attempt logging in from there.

Let me know how it goes or if you're experiencing any error messages along the way!

I'm using the app, so there's no browser. I'm using it on an Android phone. I could log in successfully this afternoon, but tonight I cannot. I'm connected to a local network, not LTE.

Thanks for the clarification! Since you're using the Paychex Flex app on an Android phone and are having issues logging in tonight while it worked this afternoon, let’s go through a few steps to troubleshoot this.

1. Restart the Paychex Flex App: Sometimes a simple restart can resolve connectivity issues. Close the app completely and then reopen it. On Android, you can do this by swiping it away from the recent apps screen.

2. Check Your Wi-Fi Connection: Ensure your local network is functioning properly. You might want to try disconnecting and reconnecting to your Wi-Fi or switching to a different Wi-Fi network temporarily if possible.

3. Update the App: Make sure you have the latest version of the Paychex Flex app. Go to the Google Play Store, search for Paychex Flex, and see if there's an update available.

4. Clear the App Cache: Sometimes cached data can cause issues. You can clear the cache by going into your device settings:
- Go to Settings > Apps > Paychex Flex.
- Tap on Storage, then select Clear Cache.

5. Restart Your Phone: If the above steps don't help, restart your device. This can resolve various temporary glitches.

Let me know if any of these steps improve your situation, or if you encounter any specific error messages while trying to log in!
