Problem with Long Text Viewer custom visual

Hey Everyone,

So i was used the Long Text Viewer visual for my previous project, and when i try to use it now it doesn't work.

This tool do not show the text that should be shown.

Actually, i check my older project and this custom visual stop worked there too.

I try to reinstall it but it doesnt change nothing.

As someone have the same problem? or maybe know what to do?

Thanks
