@rootnode "add second device'" is found in settings of an established chat profile. It's about setting up multiple devices for the same chat chat profile.

To use a different email address it's "create new profile" and then "use other server". If you have further questions or suggestions maybe better use https://support.delta.chat

@delta so, when I tried to first start the app, it only allowed on your server, no other systems. Then when I try to change it it tells me that changing accounts is not supported yet and I should check back in a few MONRHS. Sorry, but this is fishy at beet6.
