Avast One Newbie Needs Advice

Using 64 bit Windows 11

I’ve taken advantage of the special offer of Avast & just installed the apparently new Avast One (paid for version), I assume it has installed & activated correctly as it is showing in my Avast account subscriptions page.

As It is supposed for available for 5 devices am I correct in thinking this is 1 licence is for one device on your choice of machine (windows pc or mac etc) ?

Yes.
