Hi! I see you're having trouble with the PDI app failing to assign turfs. Let's dig into this together.

To get started, could you share a bit more about what exactly happens when you try to assign turfs? For example:
- Are you seeing an error message? If yes, what does it say?
- Is this happening with all turfs or just specific ones?
- Are you assigning turfs manually or using turf codes?
- Is the issue on a particular device or network?

This info will help me guide you better. Meanwhile, here’s a general approach to resolving turf assignment issues in PDI:

1. Check Your User Permissions: Ensure your PDI account has the rights to assign turfs. Sometimes, restricted permissions can prevent assignment.

2. Review Turf Status: Make sure the turfs you’re trying to assign exist and are not already assigned or in an inactive status in the Manage Turfs page.

3. Assign Manually: Try assigning turfs manually through the Manage Turfs interface to see if the problem persists.

4. Verify Network Connection: Poor or unstable internet can cause assignment actions to fail since the app needs to communicate with PDI servers.

5. App Version: Confirm that you are running the latest version of the PDI app available for your OS X version 10.15.7. Sometimes bugs in older versions cause assignment issues.

6. Clear Cache/Restart: Restart the app and, if possible, clear any cached data to rule out temporary glitches.

If these steps don’t help, there might be a backend or server-related issue. Let me know what you’ve tried or observed, and I can walk you through more advanced troubleshooting or check for service status updates1 2.

Are you able to provide more details?
