Just discovered Melia but I am flabbergasted by their tech lol

They have a 30% bonus offer showing for buying points - https://sites.melia.com/en/europe/melia-rewards-connect
In the terms, it says "Booking period: 04/11/2024 - 21/11/2024". Does it mean the offer is applicable only for points purchased during that period? So likely not available right now?

Website - The website rate is ~140k points for 1 night. I am able to arrive at the points promotion page from google search but I can't confidently say it will apply since there is no indication of promotion during checkout. Also, I am not sure how long it will take, even though the terms say 24 hours. That worries me if the room rate will still be available.
App - The app shows a lower price to begin with ~72k points for 1 night which is great. Is this kind of difference real or is it some kind of bug that would error out when I try to book? It also allows you to "buy points and book" in a single click and shows ~380 USD final price, which is a great as well!

I wonder if the 30% bonus would be calculated during offer period for "buy points and book"? It would be ~$300 USD.
Going from $600 -> $380 -> $300 is great, if it works!
