I recently purchased a subscription to Sketchup Pro and have downloaded the App, and logged in, but it does not recognize my subscription. Can’t use it.
Sign into this page, with your gmail address:
Choose Members, then look for the SketchUp Pro panel. Lower down on the page click the +Assign button, and add yourself as the user of the subscription.
Back in SketchUp you may need to sign out, then sign in, for the subscription to be updated.
