This is a great feature, well done for adding it! However, I'm a bit puzzled as to why seemingly easy bug fixes aren't addressed. There's a longstanding issue with Signal not recognizing that the phone is in a landscape orientation when taking photos, so they're rotated by 90 degrees. I opened an issue[1] and it got closed with a related-but-not-exact workaround. This impacts everyone who takes photos on Android with…
Signal is eating up 11GB of my iOS space. There is no way to clear it without completely uninstalling and reinstalling. And then the problem just resets and grows again. It’s a ridiculously consequential bug and they don’t seem motivated to even comment. Pretty sad.
They don't have the resources to store files on the cloud, even encrypted, and don't appear to have taken WhatsApp's approach of backing up unencrypted media and messages on user's third-party cloud services like Google Drive and iCloud.
You can mitigate this by having disappearing chats (current longest self-destruct time is 4 weeks), or by going to Settings->Data and Storage->Review Storage and deleting the largest files.
This isn't a great UX design, as users are not informed there is a problem, or how to solve it.
