How many times must I pay 2.99? – Bejeweled Classic HD Review

I *bought* this app for $2.99 so that I wouldn't have to deal with in-game ads, but now they've thrown that away and insist I must pay another 2.99 to get rid of this new round of ads. Will they ask me to pay for a third time when six more months go by?
