What will happen if iOS distribution certificate expired?

Question

I'm now submitting iPhone app to iTunes connect.
And I have a question about distribution certificate.

What will happen if distribution certificate expired?

Will apps which purchased by users stop running or crash after certificate expired?

Or users can't install the apps or can't download the apps from App Store after expiration of distribution certificate?

Answer 1

If distribution certificate expired then you can't submit apps in Apple Store. Existing/Submitted apps will work fine. No need to worry about it.

Answer 2

Nothing happens. Don't worry about it.
