Hi there! I’m Charlotte, and I’d be happy to help with the login issue you’re facing on your FreeStyle Libre 3 app after your spouse used the account on your phone.

To make sure I understand correctly: your spouse logged into her phone using your account details, and now you can’t connect or log into your phone’s app because it seems tied up with her use? Could you please confirm if you’re getting any specific error message when you try to log in or connect? That will help me guide you better.

In the meantime, here’s a step-by-step approach to try:

1. Log Out Completely: On both phones, ensure that the FreeStyle Libre 3 app is fully logged out from the account. Sometimes if the app stays logged in on another device, it can cause syncing or access issues.

2. Clear App Cache/Data (if applicable on your device): On Windows devices using WebKit browser to access the app, try clearing the browser’s cache and cookies. This step can refresh session data which might be causing conflicts.

3. Password Check: Confirm you both are using the same email and password correctly. If you’re not sure, try using the “Forgot Password” option on the app’s login screen to reset it securely. This way, you can make sure you have the right credentials.

4. Reinstall the App: If logging out and clearing cache don’t help, uninstall and then reinstall the app on your phone. This often resolves any app data corruption issues or stuck sessions.

5. Account Device Management: FreeStyle Libre sensor data can sometimes get linked to one device at a time. If your spouse’s phone is actively using the sensor with the account, the sensor “ownership” might be locked to her device. You need to scan or connect the sensor with your device while being signed into your account to regain access.

6. Use LibreLinkUp if Sharing Data: If your intention is to share glucose data between devices (e.g., yours and your spouse’s), the LibreLinkUp app allows caregiver connection without sharing the main account login. This can avoid device conflicts. You can invite your spouse to view glucose data through this app instead of sharing the primary login1.

If after these steps your phone still isn't able to connect or log in properly, please let me know what you see or any error codes/messages. I’ll then guide you further or arrange escalation if needed.

Are you okay to try these steps now?
