IOS Certificate (PEM): Still Necessary after update plataform credentials?

Hello!

About 20 days ago, I updated the Push Channel Settings (Android and iOS credentials). On the same screen where I did this update (Administration -> Channels -> Mobile app (AEP SDK)), I noticed an alert about the expiration of the iOS Certificate (PEM). Until last week, the option to update this iOS Certificate (PEM) was visible, but today when I tried to do the process again, that option was no longer available.

So, from what I understand, updating the credentials (both plataforms) as I did 20 days ago changed the process to token-based instead of certificate-based, right? Therefore, do I no longer need to worry about this iOS PEM certificate? ? Can I rest assured that the service will continue to function correctly?
