Will one subscription work on both ios and MacOS platforms? Or should we we have two different accounts and subscriptions?
Hi!
The subscription is for your account, you can use the same one on every platform 
Thank you.
Will projects be stored in the cloud so they will be accessible from on the MacBook after working on it from the iPad? And the reverse?
We are actively working on this, and we are planning to ship it in the next couple of months. You will be able to turn it off, but if you enable sync, you will be able to continue your design where you left it on your other device.
Fantastic! Thanks for the quick update!
