You literally cannot use it until you pay for it. What's the point of making the app free if you won't let me use at least some of it's functions?
We understand your concern. To give everyone a chance to try the app before purchasing, we allow users to use any of the features for free up to 3 times. This way, you can fully test the tools and see if the app meets your needs before upgrading.If you're having trouble accessing the free uses, please let us know, we’re happy to help!
