Hi there! I understand that your M&S app is not registering the free drinks you’ve bought. Let’s get to the bottom of this together.

To start, could you tell me if:
- You have been scanning your Sparks card or app at the time of purchase?
- You’ve checked if your app is updated to the latest version?
- This issue started recently or has it been ongoing for a while?

In the meantime, here’s a step-by-step guide you can follow to troubleshoot the issue:

1. Check Your Sparks Card/App Scan: Make sure you are scanning your Sparks card or selecting the Sparks app at checkout every time you buy a drink. Sometimes if it’s missed, the purchase won’t be tracked.

2. Update App: Go to the App Store on your iPhone and check if there’s an update available for the M&S app. Updating ensures all features work correctly.

3. Log Out and Back In: Sometimes, the app needs a quick refresh. Log out of your Sparks account in the app, then log back in.

4. Sync Your Account: If the app has a manual sync option, use it to refresh your purchase records.

5. Check Your Purchase History: Within the app, review your buying history to see if the drinks are recorded but the free drink credit is not applying.

6. Check for Any Known Outages or Issues: It’s worth seeing if others are facing the same problem. I found that some other customers have reported their Sparks cards or apps not registering coffees and drinks properly recently1.

If you have already done any of these steps, could you please tell me which ones? That way, I can guide you further, possibly checking your account details or considering contacting M&S support for backend account verification.

Let me know how you’d like to proceed!
