How to track "dead" iOS tokens?

Question

PHP

I send push notifications to users, I know that apns feedback can be used to check the "viability" of the token, but it gives the tokens that are currently relevant and will not give them back in the next request. So is it possible to somehow check the tokens that are already in my database for "viability"?

Answer 1

No way. As long as you don't try to send a push to the token, it won't become disabled.
