Hello,
I made some apps and updated them to use Il2cpp with all there platform options to continue support of 32 bit but to add 64 bit arm. I used Unity 2018.3.0f2 built with NDK 16b, Android 8 Oreo or above. On Google play store I uploaded the apk not the big symbol file. I am not sure what is wrong. The only thing i removed is the unity ad adapter and unity ad sdk.
If any one can try it. The apps are Pure Land and Xielle by Protocol 7 on Google play store. Any help is appreciated.
