Cannot guarantee authenticity of encrypted message

verymilan commented 2 years ago

Steps to reproduce

According to the reporting person (which is not actually me), this happened suddenly, it is not bound to a new session on their device.

Outcome

What did you expect?

Since end to end encrypted messages by senders who verified themself to each other and send from verified sessions, no issue or warning was expected.

What happened instead?

Old and new messages they receive to their iPhone show a grey shield, stating that The authenticity of this encrypted message can't be guaranteed on this device. This possibly is related to issues such as https://github.com/vector-im/element-web/issues/16336, however:

it also affects new messages
it at first occoured on element-desktop, but then magically switched to element-ios while it randomly occoured but then vanished on element-desktop from time to day, but appears to be permanent on element-ios
logging off and on again does not help
clearing cache does not help
reverifying to each other does not help
it partially also seems to affect their own messages from different devices
sender info shows under "Verification(? german locale)" NOT verified

From reading issues, it did not become clear to me what exactly causes this warning and it confuses and scares users affected by it. I suggest a "more info" button of some sort to understand what is happening and if possible, how it can be fixed by the user if it cannot be fixed that easily.
