There's a deliberate nit in Signal that you can't have it on both an Android phone and a no-sim Android tablet; both take turns trying to seize the role. Apparently Molly can handle both.
I just saw a blog post they’re working on this in the official app, though! Finally. Fingers crossed.
Are you sure about that?
I used both desktop and android with no issues.
Your android is the master and desktop is a slave to it, no?
I have multiple android devices and I can only log into signal on one. I can have as many desktop slaves as I want tho.
I would ideally want to not have one device being the master and the rest linked to it (e.g. Element can do that for Matrix) but that might be a too big change. And as far as I know Molly does not try to solve that.
