The app is buggy
The application consistently removes the text I have generated, and all prearranged collections of themed symbols and signs have vanished. I was compelled to uninstall and reinstall the application. This issue has recurred three times. Can you identify the root cause of this problem? An observation I have made is that when I attempt to select a text, the interface becomes unresponsive for a brief period, resulting in the sudden disappearance of all my creations and your prepackaged signs.
