Subject: Question Regarding Device Usage and Pro Plan Authorization

Dear Support Team,

Due to the nature of my work, I regularly use three Mac computers and one iPad, but never simultaneously. I would like to ask: if I subscribe to the Pro plan, will I be able to sign in and use it on all of these devices? Is there any limit to the number of authorized devices?

If such a limit exists, could you please advise me on the proper way to use the service across my devices?

Thank you for your assistance.

Kind regards

longlong

The limit is 3 devices logged in simultaneously. The moment you log in on a fourth one, one of the previous devices will be logged out automatically.
