I've got Signal on 2 computers, 1 of which I only run it occasionally. I've never had to reconnect it.

I'm not sure what's going on for you, but it seems really abnormal.

It automatically unlinks the desktop app if you don't open it for 30 days.

There is now at least a reminder on the phone app that will prompt you a few days before one of your desktop apps is about to get unlinked.

I wouldn't call 30 days "a short period of time"...If I hadn't used it for 30days, I'd uninstall it.
