If you can't see the bottom of the pop-up box on the website, it is likely due to your screen resolution. Place your cursor on the pop-up box and scroll down using your mouse wheel. If this doesn't work, or if you don't have a mouse connected to your computer, zoom into your browser by pressing the keys Ctrl and - simultaneously. It should zoom out of your screen and allow you to see the navigation buttons. To zoom in again to 100%, repeat this action with the keys Ctrl and +.
If you continue having trouble, the Invengineer elves suggest this:
Restart your device: Sometimes, simply restarting your mobile device can help resolve temporary login issues. Turn your device off, wait a few seconds, and then turn it back on. After restarting, try logging in to Portable North Pole again.
Uninstall and reinstall the app: If all else fails, try uninstalling the Portable North Pole app from your mobile device and then reinstalling it. This can help resolve any issues that may be related to a corrupted installation. After reinstalling, try logging in again.
Clear your browser cache: Sometimes, stored data in your browser's cache or cookies can cause login issues. To resolve this, try clearing your browser cache and cookies. You can usually find this option in your browser's settings menu.
Try a different browser: If you're still unable to log in, try accessing Portable North Pole using a different browser. This will help identify if the problem is specific to your current browser.
Disable browser extensions: Certain browser extensions or add-ons can interfere with the login process. Disable any extensions one by one and attempt to log in again to identify if any specific extension is causing the issue.
