The thing is, I did have encryption keys set up. The problem was that Element would repeatedly forget the very encryption keys passed by the other user, and would then have to request the keys again. Any historical message history would be permanently encrypted forever, and wouldn’t decrypt with the new view key.

After this happened about 4 times, I stopped using it, because it was impossible to maintain conversations for longer than 1-2 weeks before they’d inevitably be lost, and I’d then have to spend about an hour waiting for Element to receive the new encryption keys from the people I was contacting, even when they were already actively online.

I have no clue what was causing it, but it happened on multiple accounts, on multiple devices, all the time, and there was no conceivable fix. I’m not sure if this is fixed now, but I haven’t had a good reason to go back, especially with other encrypted messaging options out there.
