New bugs after latest bug fix release – Signal - Private Messenger Review

On iOS 11.3 after the most recent update, I can no longer use other apps while a call is in progress; when I use the Home button or app switcher, Signal instantly drops the call. The desired behavior (and the behavior prior to the most recent release) is to allow the call to continue while other apps are foregrounded.
