Terribly buggy and bad support
I signed up for the 7 day trial and a monthly subscription with the Apple anonymous email relay. Well apparently they don’t support that. Their login through Apple redirects you in a nonnative way that doesn’t allow me to use the same way that I signed up. I tried messaging support and they spent the entire 7 days of my free trial clueless. They couldn’t find any way for me to login. I only got to experience the app for one day. Again it clearly isn’t designed to be a native iOS app. The font sizes are not appropriate for use on an iPhone, especially not for a child. All the emails that I received from their automated system were also formatted wrong or missing text.
