The new update – build number G960FXXU1ARD4 and G965FXXU1ARD4 for the S9 and S9+ respectively – is rolling out in various countries at the moment, but it could be a while before it’s rolled out to all Galaxy S9 and S9+ users, especially if they only just received the last update with the April security patch.

I faced this issue couple of times (rarely) and thought it's network issue (have network issue in my area) Didn't knew it was a bug.
