Hi there! I understand you’re facing an issue where your Flex City RP gun upgrade—specifically for the Volt pistol—is not registering as completed, even though you applied all the upgrades and the task still shows 0/1. Let’s see if we can get this sorted out together.

Just to clarify a couple of things before we dive in:
- Are you upgrading the gun directly from your inventory or through a specific upgrade UI panel in the game?
- Have you recently experienced any disconnects or crashes while upgrading?
- Also, is this issue only with the Volt pistol or does it happen with other weapons too?

Meanwhile, here’s a step-by-step approach you can try to resolve this:

1. Restart the Game and Reload Your Save: Sometimes the upgrade status doesn’t immediately sync. Close Flex City RP completely on your iPhone (iOS 18.7), and launch it again to see if the upgrade registers.

2. Reapply the Upgrade: If possible, remove the upgrade once and apply it again to the Volt pistol. Make sure you select the correct weapon in the upgrade menu to avoid the bug where it auto-selects a different weapon.

3. Check for Game Updates: Developers often release patches that fix such bugs. Go to the App Store and verify that you have the latest version of Flex City RP installed.

4. Clear Temporary Data: Flex City RP might store some temporary cache that affects progress recognition. You can try closing the app, then going to iPhone Settings > Flex City RP > Offload App, and then reinstall it. This keeps your documents but clears cached data.

5. Verify Account Progress: If the upgrade progress is tracked server-side, it's possible your account data might be out of sync. Logging out and logging back into your account might help.

6. Contact Support: If none of the above work, it’s possible there is a known bug affecting the gun upgrade tracking. You could report the issue with screenshots and details to flex city RP’s support team or send an email to [email protected] for further assistance.

From community reports, there have been cases where the upgrade UI auto-selects the wrong weapon causing the upgrade not to register properly — so step 2 is particularly helpful to double-check that you applied the upgrade on the right gun1.

Let me know which steps you’ve tried or if you want me to guide you through any of them on your iPhone. Are you satisfied with the solution I provided so far?
