Hi there! I understand you're getting a challenge error related to server updates and you're unable to collect your reward in the JustPlay app. Let's see if we can get this sorted out for you.

To get started, could you tell me a bit more about the error message? Is it happening right after a server update, or randomly during your gameplay? Also, have you tried any steps so far like restarting the app or your device?

While I wait for those details, here's a simple step-by-step plan you can try:

1. Log Out and Back In: Sometimes refreshing your session helps with syncing issues.
2. Check Your Internet Connection: A stable connection is essential during server updates.
3. Clear App Cache: On Windows using a WebKit browser, you can clear the browser cache (press Ctrl+Shift+Del) and reload the app.
4. Restart the App: Close and open the JustPlay app again.
5. Update the App: Ensure your app is updated to the latest version, as older versions may not sync well after server updates.

If the issue persists, you can also try reinstalling the app, making sure your account data is saved before uninstalling to avoid losing progress.

Some users have reported that this kind of error sometimes clears up after the server update stabilizes, but if it continues for a long time, you may want to contact JustPlay support directly at [email protected] or via their website.

Let me know how it goes after trying these steps, and we can explore more advanced troubleshooting if needed! Are you able to provide the exact wording of the error or when exactly it happens?
