My created widget not set again

I make new widget design few day ago, today i removed widget from screen, them after i try to set again need primium…why???

Widgets only exist either on your homescreen or exported on you storage.
If you only have it on your homescreen and you remove it, it’s gone forever.
If you have an export on your storage, you can import it again, but to be able import a widget (yours or someone elses) you need the pro version.
You could try the add-supported version instead of the pro version:
