Hi there! I see you’re having trouble adding friends and opening the QR scanner in the HidrateSpark app on your Windows 10 device. Let’s dig into this together.

First, can you tell me if the app itself is fully updated to the latest version from the Microsoft Store? Sometimes outdated versions cause features like adding friends or the QR scanner to be disabled or buggy.

Also, when you try to open the QR scanner, what exactly happens? Does it fail to open at all, or do you get any error messages?

And for adding friends, are you trying to add friends who already have HidrateSpark bottles or inviting friends who don’t? This can affect the way friends are added.

While I wait for your details, here are some initial steps we can try:
1. Restart the HidrateSpark app completely and try again.
2. Ensure the app has permission to access your device’s camera (the camera permission is needed for the QR scanner).
- On Windows 10: Go to Settings > Privacy > Camera and make sure the toggle is on for HidrateSpark.
3. Check your Bluetooth and internet connection, as they help app functionalities.
4. If that doesn’t help, try uninstalling and reinstalling the app — this fresh start can resolve many glitches.

Once you provide the extra info about what happens when you try those features, I can guide you further.

Are you able to share those details?
