Synchronising Outlook with mobile phone

Since installing, and paying for, AVG Internet Security, I can no longer synchronise my Samsung Galaxy S9+ with Outlook on my Laptop using Samsung SmartSwitch.

WHY?

I NEVER HAD THIS PROBLEM PREVIOUSLY WITH OTHER INTERNET SECURITY PROGRAMS.

The best AVG can do is to get back to me, by email, within 24 hours.

This is disgraceful service.
