The weird thing is, you kinda can send URLs through Flow in bulk? But also not? For some reason, when I select my tabs and copy the links all at once through that, it will only paste one link into Flow, but if I paste it literally anywhere else, including the app's own address bar, then all the links come up. If I then cut/copy-paste from there, all the links paste into Flow and embed properly! I seriously don't know what's up with that. But yeah, they really need to go all the way with integration, not stop halfway like this.
