SayHi discontinued, any idea why?

The SayHi translation app (from Amazon) has been discontinued as of 8/5/24. My existing install no longer works, and the app is not available on the stores. The app main page just has the discontinuation notice, but no explanation.

I still have DeepL to fall back on, but had found SayHi to be a good alternative. I miss it.

Does anyone know why this was discontinued? Any idea if Amazon is expected to release a replacement?

Any suggestions for a replacement? What has worked for you?
