This’s my message.

Always can’t connect, even if it’s slow to connect to the network
My system MacOs 10.15.3 (19D76), SecureLine version 3.8.0(48336).
This has happened in the last two days.A few days ago, it was possible to connect, but it was slow.
I want to know how I can continue to use it

Why is there no one to solve and reply

Too bad experience after payment

No technicians, no after-sales support
