For real. Removing SMS support was the biggest mistake they could have made IMO. Even though they’re right that SMS is stupidly insecure, that feature was crucial to getting people to adopt the app. As soon as they removed it, basically everyone I had convinced to install it dropped off. I still haven’t found a trustworthy replacement myself (open to suggestions), so I’m just using Signal alongside the stock Graphene messages app for SMS.
