Can’t reinstall after purchase – Magic Fingers: Amazing Paint! Review

I get it that it’s $1.00 but its the principle of it... I purchased this app twice now to be ad free. The first time it didn’t make a difference. I still got the ads. The second time (change of device -fine ?, it’s a $1.00) BUT shouldn’t it be kept in my purchased list of apps? It’s not there. Due to a “lemon” phone, I’ve had to get my phone switched out so for me to have this ad free, I will AGAIN have to pay.... so now a $1 purchase has gone up to $3...
