If you have problems with E2E (end-to-end) encryption, you can reset the settings.
To do this, navigate to your profile picture or your initials in the chat at the top left, open the menu by clicking and then select “My Account”.
You will also find your security settings under My Account.
If you have problems with E2E encryption, you can reset it here. You will then be logged out of the chat server and can log in again by clicking on "Enter chat".
A new encryption password will now be displayed here. You should remember/save this. Alternatively, you can change it.
