Can't sign in to Nebula app

Can’t sign in to the Nebula app, even though I’ve used it before - says it will send me an email to verify who I am, but I never get one. Pretty sure I’m using the right P/W, positive I’m using the right email address. Tried uninstalling and re-installing the app, but same reult - so many problems with this app !
