Comment 45 for bug 1616650

This issue also causes massive data loss when using the signal-desktop (Electron/Chromium) snap. I just leave it running all the time. This time it was running for 20 days. (Why would I ever quit it?) At some point the snap refreshed in the background. The next time I opened Signal, it popped up a huge dialogue with a bunch of unicode squares I obviously could not read and the app became non-functional. I quit it and restarted, and none of the messages I had received since the refresh were saved any longer and all of my user preferences were gone.

I activated the refresh-app-awareness option after discovering it just now, but there's no way I'm going to magically remember when the last time I restarted the app was, to guess whether it had been 7 days or not and I need to manually restart it.

Snapd MUST add an option to allow manual updates, along with a warning to users to restart their apps before updating.
