Synchronizing Ipad and mac

Hi Margin Note team/community

I just paid for premium on my ipad, however when I access Margin Note three on my mac laptop I still have an old version (trial account) of margin note. How do I sync my account across all devices?

I assume I dont have to buy margin note 3x times as its a subscription. I just want to know how to sync it across all devices.

Thank You

You need to enable cloud sync in your settings.
