Hi there! I see you're having trouble with your collections not showing categories in the iCollect Everything app on your iPhone. Let's get this sorted out together.

Just to clarify a bit more:
- When you say "collections not showing categories," do you mean that when you try to switch collections, the list of collection types (like Books, Movies, Video Games, etc.) is empty or missing?
- Also, have you recently updated the app or changed any settings before this issue started?
- Are you logged into your account properly, and does this affect all collections or just some specific ones?

To start, here’s a simple step-by-step you can try:

1. Restart the App: Close the iCollect Everything app completely and reopen it. Sometimes this refreshes the data display.

2. Check Internet Connection: Make sure your iPhone has a good internet connection (Wi-Fi or cellular) because the app needs it to load your online collections properly.

3. Log Out and Log In: Try logging out of your iCollect account within the app and then logging back in. This can refresh your data and solve display problems.

4. Update the App: Go to the App Store, check if there is an update available for iCollect Everything, and install it if so. Updates often fix bugs related to data display.

5. Rebuild Cache/Data: If the above don't help, in the app settings, look for an option to clear cache or data refresh. This can fix corrupted display issues.

If you've tried these or if the problem persists, it could be related to a bug that the developers know about. There was a recent fix that addressed missing custom collections in dropdowns and category lists, so making sure your app is updated to the latest version might solve it1 8.

Does this help? And have you done any of these steps already? That way, I can guide you even further!
