Subscribed to free trial, all pro features still locked – Crop Video Square Editor Review

Was trying to crop a video and mirror the sides for my Snapchat. To do the mirror effect you need Pro features. I saw a free trial was going and subscribed to do this real quick. Now it says I have a subscription (monthly) but all pro features are locked. If the pro features worked I would probably keep my subscription because this app has many functionalities, but I fear even if I purchase pro now it will not give me the features. Please fix this!!!!
