Free trial doesn't work
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.

Constantly crashes
Response from developer
Hi, thank you for your valuable feedback. We always test the app before we release new updates, however, since our team is very small, issues do creep in sometimes and we try to fix them ASAP. If you could please send us more details, e.g. your iPhone model, to hello@sylby.com, then we will work on fixing these issues right away.

Hallo, es tut uns leid zu hören, dass die App bei Ihnen nach dem Update nicht mehr funktioniert. Könnten Sie uns bitte mit mehr Details (z. B. iOS-Modell und Version) an hello@sylby.com schreiben? Könnten Sie in der Zwischenzeit bitte die App deinstallieren und erneut installieren und es erneut versuchen? Vielen Dank und beste Grüße, Team sylby.
