Phased release of a version while the previous phased release is not finished

I was not able to find info regarding this situation in the official docs.

What will happen if a version was not yet released to all, and a new version is phased released?

For example if I am phased releasing version 2.0. On day 3, when only 5% of the users have this version, I discovered that this version has a bug. I paused the release of 2.0 and created a hotfix version 2.1. What will happen all the users who did not receive 2.0 when I start phased release of 2.1? Will they get an immediate update to 2.0 or will they skip this version?
