Solution to gray-out of ipad/iphone mobile phone positioning service

1. Click "settings"-"general"-"Access restriction" on the desktop on the ipad or iphone. The details are as follows:

2. You need to enter the password to access the access restriction. Here we will enter the unlock password.

3. Then we will see a [positioning service] in this interface. We just need to click to open it.

4. Then, modify the current positioning service to the option "allow modification".

5. After the settings are complete, we turn on the "locating service" option on the iPhone again and find that you can set it manually.

Now, let's try again to find out if the service can be used normally. If it still doesn't work, we can try restarting the mobile phone or upgrading the ios system.
