They should have made this a paid app at first so the people that really do want to use it, wouldn't have to wait as long to use it.
Kinda fishy how the app is being rolled out.
Do you understand how the app actually works?
It uses their servers to copy and place your email.
They had over 700,000 people before they released the application. They did not want to be slammed because they had no idea what kind of release was going to happen.
You can not test this kind of scenario so they went the conservative approach.
Instagram and other apps had shutdowns and other problems because of this.
This is the smart way to do it.
Also on the paid app part of things. Their plan is not to have a paid application. They want to sell services with it.
Not sure what services exactly, they talk about collaboration, so maybe some from of email project management.
