Hi there! I see you're having trouble with the Simply Plural app not working on your iPhone with iOS 18.7. Could you tell me a bit more about what exactly is happening? For example, is the app not opening at all, loading very slowly, showing an error message, or something else?

In the meantime, I can suggest some quick steps that often help fix this kind of problem:

1. Restart your iPhone: Sometimes a reboot clears things up.
2. Check your internet connection: Make sure you’re on stable Wi-Fi or cellular data.
3. Update the app: Open the App Store and check if there is an update for Simply Plural.
4. Clear the app cache: iOS doesn't have an explicit cache clearing option, but you can try deleting and reinstalling the app to clear any corrupted data.
5. Check if the servers are down: Sometimes the app’s backend servers might be having problems. This has happened before with Simply Plural and others have reported connection issues around server downtime.

If you’ve already tried some of these, please let me know which ones, and we can dig deeper from there. Also, if possible, share any error messages or specific symptoms you see.

Looking forward to helping you get this sorted!
