Hello 
,
what exactly is the problem?
Tap on “SE CONNECTER AU COMPTE COURRIEL” and enter your email account details.
I did but it says that an error has occurred
Can you tell me step by step how to login or create an account on the app ?
Which provider do you use?
If the name is in the database, it is usually sufficient to simply enter the address and password. Otherwise enter the requested data under “Avencé”.
You can find this information on your provider’s website.
With some e-mail providers it is necessary to activate IMAP on the website or to create an app password. This must be entered into Delta Chat.
In such a case, the normal password will not work.
In case you can see how to set up the account from
https://providers.delta.chat/
if you use one of the providers in the list
