Pity it crashes for me 100% of the time when opening on an older iPhone. Haven't been able to receive my messages for over 2 months - which is insane for a messaging app (I'm not even sure if I'll receive the messages if/when they ever fix it). This is despite me contacting support and sending the crash logs to them when it happened. As much as I'd love to support Signal and switch everything from WhatsApp - it doesn't seem like a wise choice if this kind of thing is a possibility.
