Hi there! I see your Zangi app is stuck on a message to wait for an update and won’t open, plus you can’t delete it. That can be tricky. Just to clarify a bit: Are you trying to update the app via the App Store, or is it trying to update automatically and failing? Also, when you say you can’t delete it, what happens when you attempt to delete?

In the meantime, I’ll guide you through some steps that usually help in this situation on an iPhone with your iOS 18.6:

1. Force Close the Zangi App:
Double-click the Home button (or swipe up on models without a Home button) to bring up the app switcher, then swipe the Zangi app off the screen to quit it completely.

2. Restart Your iPhone:
Press and hold the side button and either volume button until you see “slide to power off.” Turn off the phone, wait about 30 seconds, and turn it back on.

3. Check for App Store Updates:
Open the App Store, tap your profile picture in the top right, scroll down to see if Zangi is listed under pending updates. If yes, try tapping update. Sometimes it helps to be on a strong Wi-Fi connection for this.

4. If Update Won't Proceed and Delete Isn't Working:
- Go to Settings > General > iPhone Storage.
- Find Zangi in the list, tap it.
- From here, try tapping Delete App. This often works even if the icon doesn’t show the Delete option normally.

5. If Step 4 Fails, Try Offloading the App:
In the same storage screen, if “Delete” isn’t responsive, tap Offload App. This frees up the app’s space but keeps its documents and data. Later you can reinstall it fresh.

6. Make Sure Your iOS Version is Up to Date:
Go to Settings > General > Software Update to confirm iOS 18.6 is fully installed and no incremental patches are pending, as sometimes app updates require the latest OS.

7. Check Available Storage Space:
Still in iPhone Storage, confirm you have enough free space; Zangi updates might stall if space is low.

These steps usually clear update and delete block issues on iOS1.

If tried and nothing changes, sometimes a deeper reset or contacting Zangi support may be next, but let’s see how this goes first. Could you try these and let me know? Any error messages or behavior during these steps would be great to know too!
