What is the reason for the failure to update Apple qq address book?

I guess it's a permission restriction. For details, please refer to the following steps:

1, open qq, and click on the top left avatar.

2. On the displayed page, click to select the settings at the lower left.

3. Click and select About QQ and Help to proceed to the next step.

4. Select the version update option to see if there is a version that can be updated.

5. Click Update, wait for the client data to be synchronized after the download is completed, and it can be used normally.

6. Then you can open the phone settings, general, iphone storage space, empty the qq cache, and download and update the mobile qq again.
