I would like to be able to find out why my account says I have 2 devices when I only have 1. Simple question that a Customer Service Dept could easily help with.
Well you aren't actually talking directly to customer support, mostly it will be avast users helping others.
It also is off-topic for this topic about Avast Features and should really have been in its own new topic.
That said aren't you getting any more details ?
When you talk of devices, that isn't something I'm familiar with in regard to Avast Products, more so in regard to two licenses/subscriptions, etc.
A screenshot of this notification might help ?
