Do you constantly have to verify your applications?

Is anyone experiencing their paid app constantly in demo mode and have to be activated/logged into account online to be verified? I noticed this with photo ai, Gigapixel and ai video. Sometimes they can’t be updated unless it’s verified. You’d think the software knows it’s not a demo version. but perhaps what we have are all demo versions that requires constant online check to see if you have paid then removes the demo lock for a few days and if it hasn’t checked in a while, it slaps back on the demo lock.
