Disallowing to edit file using demo version 3.3.5

I have downloaded the demo version from link: www.radaeepdf.com/download/download-prev...e/19-radaeepdf-3-3-5
Then i have integrated the libraries in my application.
For few days everything works fine also issue for text rotation fixed.
But now its stop working and even disallowing to edit file.
Is this related to licensing, Please let us know in detail soon?

Hi,

do you see the Radaee watermark on your pdf file? If you don't see it, the license is correctly activated.
Can you reproduce this issue also with demo project?

License is statically validated and have not any time limit.
Once the key is correctly calculated for your bundle-id it continues working.
