Why is the number of sent push messages higher than the number of recipients in the campaign?

Mobile or web push tokens are associated with the app or device (browser) on which the user has given consent to receive notifications. Users may have more than one token - this depends on the number of apps or devices (browsers) they use and on which they have given consent for notifications. As part of a campaign, pushes will be sent to all possible tokens for a contact.

Example: a user uses 3 browsers (Chrome, Firefox, Edge) on all of them, they have given consent for notifications. 3 tokens have been assigned to them. During the campaign, 3 push messages will be sent to the user for each token, and automatically from 1 person there will be 3 recipients.
