In 95% circumstances, “unsupported on gadget” has a cause. It means your gadget is missing essential options, libraries, and (hardly ever) efficiency. Even in case you sideload it, there’s excessive probability it will not work on unsupported gadget.
… Which isn’t associated to the problem you’re dealing with. Sadly, with safety like this, the one manner is to formally obtain the app from trusted supply (strive another retailer, like Amazon AppStore, Huawei AppGallery, Samsung Galaxy retailer, APKPure, TapTao, QooApp and others).
Or dive deeper into shady darkness of app pirating, and seek for modded APK. However I strongly advise in opposition to that.
