DllNotFoundException in Unity android app

What is the license key type you are using? Node-locked or hosted floating?

Where can I see this?

On the license page, most probably you are using a mis configured hosted floating license.

Hi Adnan,
I Dm’d you with further information

Hi,

Can you try an activation today on the device? The license configuration is ok.

I’ll test it and get back to you.

The license can be activated, but when closing the app and entering again, you have to activate it again. Sent you a pm with all the info
