Activation checklist

License keys always start with IHC-.
Paste the whole key, including every dash.
Use the same browser profile where you want Pro enabled.
After activation, look for Pro active, your Pro plan, and Manage license in Settings.
If the license is already active on too many devices, manage or revoke an old device from the license email link.
