Apple developer. Will having applications break when updating the Provission profile, certificates?

Question

Apple Developer Program

Hello!

Not so long ago I ran into building an in-house application for iOS and now I need to change some parameters, but there were questions whether this would affect the work of already assembled applications.

1. When changing the Provission profile (adding a certificate to it, etc.), as I understand it, the profile will be updated and its date will be updated, etc. Does this somehow affect the application installed by the person, built with the old version of the profile?
2. If profiles, certificates (development, push, etc.) expire, will the already installed application break down in a person? Will it stop running? Or will it stop installing if not installed?

thanks in advance
