One both my tablet and phone, Android moans about being unsafe, I blunder through and Install Anyway, it then moans about it being for a prior version of Android and has another moan, (both my devices are on 14) then it pretends to install Cubsuit it but there is no sign of the app. Hmph! 

Another PDF reader has squatted on the CubeSuite app name in the Google Play store, and they want money for a PDF reader - cheekily they mention the Page Turner.

My ancient, inherited, iPad Air is condemned to MacOS 12.5 forever more - it rejects the install for the CubeSuite.
