A Pro VIP yearly upgrade applies to all events within a single nonprofit profile, specifically the one you are logged into at the time of the upgrade. You can confirm this by checking the profile name in the upper right corner of the dashboard.
If you want to upgrade other organization profiles you manage, switch to a different profile linked to your email address by using the dropdown menu in the upper right corner. Then, navigate to "Upgrade Options" to proceed. The money-back guarantee applies separately to each profile.
For convenience, you can link multiple profiles to the same email address. However, each profile is treated as a separate entity for verification, event listings, donation activity, recordkeeping, and billing, as they represent distinct organizations in the real world.
