Unable to decrypt messages in chat

[Insaf01]

I am having trouble reading some messages in chat rooms via pm cause I keep getting this message

** Unable to decrypt: The sender's device has not sent us the keys for this message. **

I am using riot on the web via chrome.

Please help me fix this problem

Same problem here, I cannot read from Element Web my own messages sent from Element Android. Both devices are verified.

Same problem for me and for a colleague of mine. This is the source of decrypted event

{
  "type": "m.room.message",
  "content": {
    "msgtype": "m.bad.encrypted",
    "body": "** Unable to decrypt: DecryptionError: The sender's device has not sent us the keys for this message. **"
  }
}

{
"type": "m.room.message",
"content": {
"msgtype": "m.bad.encrypted",
"body": "** Unable to decrypt: DecryptionError: The sender's device has not sent us the keys for this message. **"
}
}

Going through the same.
Has anyone find the solution yet?

I signed out and signed back in to Element on Windows 10. Now I see this same error on all old messages. My homeserver is matrix.org.
