VPN hangs intermittently since last Avast update on 21st april

Hi everybody
Avast did a version update on my system (Windows 7) on 21 st april and the VPN does not work anymore
First connection to any web site takes decades and when it starts working, it just hangs still after a few minutes of normal browsing
Could not find how to send a message to Avast support
I have desintalled and resintalled the VPN, but no luck
has anybody an idea of what’s going on and how to fix it ?
Thxs
