In iOS/iPadOS, if I open a share sheet, for example this one in the IMDb app:
I can select a recently used group chat (circled). However, if that group isn’t in the recent list and I just press on the “Messages” option, it seems I only have the option of messaging individual contacts. Even starting to type the name of a group chat does not yield any results. Is there a way of selecting another group chat without just individually selecting all the contacts in that group (which may not be possible)?
