If the cause is a random database key collision you can't immediately discover it obviously. You have no idea what was causing it, so you'd have to do logging.

Yeah I'm sure they just decided to abandon their core value because they wanted to hurry a feature they had advertised to no-one, and were thus in no rush to deploy.
If this was an actual issue I wouldn't care if it was my own app, I would pour a truck load of bricks on top of that.
Nobody mentioned anything about 'guarantees', this is a matter of urgency and priorities.
I don't care if this was a 'rare' issue, Signal knew this was open for half a year and what were they doing? Testing cryptocurrency payments.
If security was really that important to Signal, where was the urgency there?
If this was any other app that did this (especially Facebook) you'd rain down on them like a ton of bricks.
