Thank you for reporting!

This seems expected to me because armeabi-v7a is x32 architecture and translations runs on WebAssembly, which requires x64.

To confirm, when running armeabi-v7a:

• Go to https://webassembly.org/features/
• Either Relaxed SIMD or Fixed-width SIMD should be checked to indicate support.

If WebAssembly isn't supported, then this is as expected.

There will likely also be a log in adb logcat of Success requesting engine support. isEngineSupported: false.

Thanks Olivia for explanations! Confirming that Relaxed SIMD and Fixed-width SIMD are not supported on armeabi-v7a build under Sony Xperia Z5 with Android 7.1.1.
