I understand how inconvenient it can be to run into login issues, Pwoolly. Rest assured that I will help you sort this out.

The error message you're encountering can be due to a connectivity issue with the app or a temporary glitch. Here are several troubleshooting steps you can consider to fix it:

• Ensure you're connected to a stable Wifi connection or good mobile data.
• Ensure you have the latest version of the app installed on your device.
• Clear the app's cache and data.

To clear the app's cache for Android:

1. Go to the phone's Settings and select Apps.
2. Find the QuickBooks Self-Employed app in the list.
3. Pick Storage, then tap Clear data.

To clear the app's cache for iOS:

1. From your phone's Settings, choose Settings.
2. Click on General and choose iPhone Storage.
3. Find the QuickBooks Self-Employed app in the list.
4. Select an app that's taking up a lot of space. To free up the Storage without deleting the documents and data for the app,
5. Click on the Offload App.

I just got a new phone and am unable to login via my new phone. App still works on my old phone though. I did uninstall and reinstall the self-employed app, cleared the cache etc., but I am still getting the "parameter specified as non-null is null" error message. 

Good afternoon jrbrumby,

Welcome to the QuickBooks Community! Thank you for clearing the cache. I have two questions that can assist us further in helping you.

1. Are you using the QBSE app and are in the US?
2. Are you using an Apple or Android?

I am looking forward to your reply! See you soon. 

I am having the same problem with my android phone. I have tried clearing the data and cache as well as reinstalling.

Hi there, @AdkinsHI. I appreciate you taking the initiative to perform troubleshooting steps to fix the error. I'll share information about why you're experiencing this issue and provide you with a resolution.

The QuickBooks Self-Employed application was discontinued on the 24th of March 2024. Since you mentioned that you're reinstalling it, I'd like to ask where you re-downloaded it. In order to operate the application, you'll need to ensure that you get it from the app store account you used to install it.

However, if you upgraded your phone and reinstalled it, make sure it came from your App Store account history. You can refer to these links for instructions to ensure you obtained it from the same store account:

• Redownload apps and games for your Apple devices from the App Store
• Reinstall & re-enable apps from the Google Play Store
