Hi, Let's say I want to send one payload to 1000 users, can I encrypte it before passing to Subscription::create ? I aim to reduce the sending time. Thanks.

Hi,

Since the encryption of the payload is done using the user public key, it is not possible to encrypt only once, apart if you're sending the notification a thousand times to the same user.
