What type of Android device are you downloading it on?
I just reloaded on a new phone, and even though it is a older program, it still works fine

I have a samsung 22 ultra, when I go to the link you gave, it says " this app isn't available for your device because it was made for and older version of android, I also tried on an older samsung tablet from 2015, and it says the same thing. I don't get it. I also tried on my ipad.
Interesting. I have a Samsung A42 and had no issues re-downloading. For the ipad there is a separate program called Flamelet
I looked up the APK dynamics on the S22 and it may have a source block on JWildfire
