OK, I'm gonna have to tag @Mer__edith here, because this is simply not viable.

As far as I can tell, as a user you are platform-locked forever when using Signal - I get that it's for complicated technical reasons but the fact remains that it just isn't long-term sustainable that a user can NEVER decide to move off of whatever OS they happened to start on.

The longer people use this app, the worse this limitation becomes. The time to fix it is now.
