A Pro Annual upgrade applies to all events within a single nonprofit profile, specifically the one you are managing as indicated in the upper right hand corner of the dashboard. If you wish to upgrade other approved profiles, you can switch to another one connected to the same email address using the dropdown arrow in the upper right corner, then upgrade each separately. The money-back guarantee applies to each upgraded profile, independent of the others.
We enabled linking of multiple profiles using the same email address for your convenience. However, because they are separate entities in the real world, they are treated as separate entities for verification purposes, listings, donation activity, and payments.
