If the cursor has stopped at an edge, the first two answers cover almost every case.
Allowing Input Monitoring the first time
The first time you open CursorCrossing, macOS asks you to allow Input Monitoring. The app needs it to see where the pointer is. Open System Settings, go to Privacy & Security, then Input Monitoring, and turn on CursorCrossing.
Nothing you type is read. The app only receives mouse movement.
The cursor stopped crossing after an update
In System Settings, open Privacy & Security, then Input Monitoring. Select CursorCrossing and remove it with the minus button. Add it again with the plus button and turn it on. Crossing resumes straight away; you don't need to restart anything.
What the free trial is
The trial is 7 days on the monthly subscription, and Apple runs it. Nothing is charged until the 7 days end. Cancel before then in System Settings, under your Apple ID, then Subscriptions, and you pay nothing.
Cancelling the subscription
Open System Settings and click your name at the top, then Subscriptions. Choose CursorCrossing and click Cancel Subscription. You keep crossing until the end of the period you have paid for.
Restoring purchases on a new Mac
Install CursorCrossing from the Mac App Store with the same Apple ID. In the app's welcome window, click Restore Purchases. Your lifetime purchase or running subscription comes back at once. Family Sharing members restore the same way.
I bought lifetime and I'm still being charged
Apple gives no way for an app to cancel a subscription for you, so CursorCrossing says this at purchase and offers to open the subscriptions page. If the subscription is still running, cancel it in System Settings, under your Apple ID, then Subscriptions.
Drawing a portal
Choose Edit Portals from the menu bar item. Press near an edge of one display and drag along it to mark the stretch you want to cross from, then draw the matching stretch on the other display. The two are paired: a point a third of the way along one lands a third of the way along the other.
Displays that meet at a corner need two portals, one for each leg of the corner.
The three modes
Automatic crosses wherever macOS would stop the cursor and leaves everything else alone. Automatic and portals does that and also uses the portals you have drawn. Portals only crosses only through your portals, so native movement is untouched everywhere else.
