The developers simply deprived people of the opportunity to try out their app before paying. You can only see what they offer after you buy a subscription.I understand their decision. Obviously, they ran out of money and the deadline was tight. They decided to release an unfinished,raw product and sell it. After all, if there had been a trial period, no one would have stayed here and definitely not have bought a subscription. It's very simple. My grade is zero.
