I pay for the Adobe CC subscription every month. I am not sure why you are adding the extra advertising to the end of my Youtube video when exported from the Adobe Premiere Clip, but I would appreciate it not having that advert at the end. I am signed in when using the app.
How can I remove this?
You can remove the Clip bumper by going to the App Settings (button at the top left of screen) > Preferences > Toggle off 'Add Bumper'
You're good to go!
