I just got the app and it has been malfunctioning already – Smart Post: Schedule Media Review

Hello, I just downloaded the app and it has already malfunctioned. I thought this app will be very efficient for me since I have Facebook groups that I'm in charge of and I would like to post stuff to keep everyone up-to-date. But it seems this app doesn't have the capabilities that I thought it did. I hope you can fix the app because I had high expectations for it. It has many bugs and the loading page needs to have a way to contact tech service.
