Very bad for managing more workspaces

If you have more emails and workspaces, it refuses to let you log in. Email reseting password are not send. Seems that slack has some outage. Even if entering password and email combination correctly, it is not working. :-( really poor work Slack team. Cannot relly on such a sSW and create outage of entire project team. Good bey Slack, deleting.
