seats.aero pro review - not worth it

guys, want to post my experience on using seats.aero Pro. unfortunately it hasn't worked for me at all. They aren't transparent about their capabilities on the website before you sign up for pro. They don't support 1-stop combinations on most alliances so you have to set alerts based on 2 legs but the airlines typically release award seats for the whole journey and searching 2 separate legs doesn't get you much. Overall, their search function works ok and I'll stick to their free service in the future as there's literally no extra value I gained from pro and their alerts service
