Purchased Premium (lifetime) a few years back, which meant no ads. In recent months they introduced Premium Plus, and ads started showing up in my Premium account. This was annoying, because Premium was meant to be lifetime ad-free. The latest version puts Premium Plus ($19.99 per year) at the forefront, and most of the useful data (like hourly UV index) went from free to paid content. This was a bait and switch maneuver and feels quite dishonest.
