Pairing the iPhone app
The iPhone app is free and opens a workspace you already have. On your Mac, open Current, then Settings → Devices, and scan the code with the app. In a Teams workspace, open Settings → Devices in the browser. Codes work once and expire after 10 minutes; make a new one if it fails.
Plans and billing
A Team workspace's plan is in Settings → Billing, for its owner. It opens Stripe for cards, invoices and cancelling. A cancelled plan lasts until the end of the period you paid for. See pricing.
Bugs and requests
In Current, choose Feedback in the sidebar to send a note with a screenshot. On the Mac, Help → Copy Diagnostic Report copies details you can paste into an email.
