I’m not sure how you arrived at that conclusion, and I don’t think it’s accurate. My Motorola moto g7 from 2019 is running 64-bit Android 10 and doesn’t have any apparent problems with the v3x app. I don’t think @browndwz would get the app to install at all—much less launch—if the phone in question was actually running a 32-bit OS.
I agree on the face of it, especially after reading @Seapup’s post in another topic. I imagine that at least part of the decision is driven by OS providers deprecating 32-bit versions of their OSs, and I do think that makes sense for long-term sustainability, though Android (Go edition) is 32-bit only and has versions that are currently supported, so in my mind the move to abandon development of a 32-bit version of the Wyze app seems premature.
