Hi there! I see you're having trouble adding an item to your bag on the boohoo site. I'd love to help get that sorted for you.

To start, could you tell me more about what happens when you try to add an item? For example:
- Do you get any specific error message, or does the site just not respond?
- Have you experienced this issue on your iPhone's browser with iOS 18.5 before, or is this the first time?
- Are you signed into your boohoo account while shopping?
- Have you tried refreshing the page or restarting your browser app?

Once I have a bit more detail, I can guide you step-by-step to fix it. In the meantime, let's try these quick checks:

1. Clear your browser cache and cookies on your iPhone. Sometimes old data can cause issues with adding items.
2. Ensure you have a stable internet connection, maybe switch between Wi-Fi and cellular to test.
3. Try adding the item again after a quick page refresh.
4. If you have an app for boohoo, consider trying to add the item there instead of the browser.
5. Confirm the item is still in stock—sometimes items go out of stock and can't be added.

Let me know what you observe, and we'll take it from there!
