@Em0nM4stodon I wish that when people discuss pros and cons of Signal, they mentioned that there is absolutely no backup option on iOS. Lots of iOS users get burned when they lose their phone or accidentally uninstall the app and find messages with loved ones are completely gone. If reviewers would mention this, fewer people would get burned by the issue.
You could add to this post itself that Signal is not a good option for iOS users who care about preserving their messaging history.
