Now the staff who use iOS are going to be pissed when they find out chats cannot be backed up or transferred to another device and that rejoining groups on a new device is going to be painful. That’s assuming message delivery works fine and that inadvertent “device changed” notifications don’t pop up when nothing has changed. I’d bet that these people will soon find different ways to communicate just to avoid some pains and probably put up a pretense of using Signal.
Anecdote: Personally, I’ve been using Signal for some years with a few different group chats. The number of times people in those groups talk about how bad Signal is and want to avoid it hasn’t changed much (these people use a mix of iOS and Android). All those groups are quite silent because people don’t want to use it.
Edit: Security without ergonomics doesn’t help. And Signal is still behind on that front. As someone else here pointed out, they could’ve chosen Wire, which has a better UX and has E2E chats syncing across devices.
