my only complain about containers is that it doesn't work well when you want to authorize an app. For example, I want to sign in with Google on my Zoom app but since i told them to always open google domain on my B container, it opens it in B while my gmail account for personal use is in A container. My workaround for now is to change the default browser app and revert it back once i'm logged in. I wish there was a solution for this.
