Hello,

If you've already replaced the Development License Key with the Basic License, and rebuilt the app, then I would suggest you do a complete uninstall of the previous app version from your device. Vuforia Engine stores a license key in the app's local file system and this may need to be deleted to remove the watermark.

Thanks,

We trying to install Unity, trying to run in other workstation, watermark still in.

Hello,

If you can DM me your license key (as copied from the Vuforia Developer Portal) I'd be happy to give it a try.

Thanks,

Vuforia Engine Support
