Is Avast One really Oven Ready?

Avast One is being shoved out at traditional Avast users but do they realise that it is a long way from acceptably usable by the average user, especially those who use email clients like Thunderbird?

I mistakenly mouse fumbled the invitation to update to Avast One and paid for my inattention with half an hour of restoring Avast Free.

Yikes!
