Hi there! I see you’re getting an “oops, invalid” message in the Pioneer Press e-Edition app after updating your iPhone to iOS 26.1. Let’s see if we can get you back on track.

To start, could you tell me if this error appears immediately when you open the app, or does it show up when you try to access a specific section or feature? Also, have you tried any steps like restarting your phone or reinstalling the app already?

In the meantime, here are a few straightforward steps that often help with app errors after a system update:

1. Force close the app and reopen it:
- On your iPhone, swipe up from the bottom and pause (or double-click the Home button if your model has one) to see the app switcher.
- Swipe the Pioneer Press e-Edition app off the screen to close it completely.
- Then, open it again and check if the error still appears.

2. Check for app updates:
- Sometimes apps need to update to work right after an iOS update. Open the App Store, tap your profile icon, and scroll down to see if there’s an update available for Pioneer Press e-Edition. If yes, update the app.

3. Restart your iPhone:
- Hold the side button and either volume button until the slider appears, then slide to power off. After your phone shuts down, hold the side button to turn it back on.

4. Reinstall the app:
- Press and hold the app icon, tap ‘Remove App,’ then ‘Delete App.’
- Go back to the App Store and reinstall the Pioneer Press e-Edition app.

If you’ve tried some of these already or the problem persists after going through them, let me know. We can dive deeper into the issue, including checking potential account or network problems.

Are you happy to start with these steps?
