You bought Pro. Activate it in two steps.

No account, nothing to download again. Do this once, in Switchman's settings:

Opens Switchman and activates Pro in one click.

1. Open Switchman, go to Settings → About.
2. Enter the email you just paid with, then enter the 6-digit code we email you.

That is the last time Switchman talks to our server for Pro. From then on the receipt is verified locally. iCloud sync is a separate, optional Pro switch and talks only to your own iCloud.

No email after a few minutes? Check your spam folder, then try the email again in Settings — the code is re-sent, three times every five minutes.
