🚑 Early Morning Tech Rescue – Solving a Susu Web App Token Issue
📖 The Incident
Early this morning, just after dropping my wife off at the Long Island Railroad station, I received a panicked call from a user of my Susu web app. They reported being locked out of the system despite having a valid token. I assured them I would troubleshoot as soon as I found a parking spot.
They quickly sent me a screenshot of the issue:
🛠️ First Attempt
A few minutes later, I issued a new token for the app and informed the user that the problem should be resolved. Unfortunately, they called back to report that the issue persisted, even after trying the app link in their phone’s browser.
🔍 Root Cause Suspected
Based on experience, I suspected a cache issue. Cached data often interferes with new tokens or updated links, especially on mobile browsers.
📱 Solution: Clearing Cache on iPhone Safari
I guided the user through clearing their phone’s browsing history and website data. Here are the steps:
- Go to Settings

- Tap Safari

- Scroll to the bottom of Safari settings
- Tap Clear Cache

- Tap Clear History

Side note: You can also clear cache for individual apps, but not all apps support this. Deleting an app removes its cache, settings, and data.
Tip: Regularly clearing your cache improves browsing performance and frees up storage space.
🎉 Resolution
After following these steps, the user was overjoyed that the issue was resolved. 😹
