Thieves

You guys are bunch of thieves making money off people. I downloaded the app but i signed up using a browser on my computer and made payment for 3 months that cost $14.99 but after making payments, a pop up message came and it said there were going to send me an email on how to use it and up to date, nothing has popped up in my mail also I’ve download the app but i can’t sign in with the same information i used in signing up on my computer

Non functioning features

Some of the functions do not work, and it makes it not good to use. The fact that I pay for a subscription and buy credits too. Pictures don’t go through as well
