Free trial doesn't work

Whenever I try a free trial, I always go in and cancel the subscription right away so I don't forget easily (and it will say "subscription continues until [end of free trial date]"), and then if I end up loving the app, I re-enroll in the subscription before the trial ends. I did the same when trying out sylby, and even though my free trial doesn't end until June 8, I am locked out from all "pro" activities in the app. I have never seen any other app do this when someone cancels a subscription and think it's an unfriendly business practice. I guess I won't be trying sylby pro, and I certainly won't be subscribing, since they don't want to let people try it without risk.

Doesn’t work

I tested it out on a relative who is a native German speaker and it was flagging him as mispronouncing things
