5 months ago, Amazon announced that they will discontinue their dash buttons. Now Amazon say that their buttons would cease to work by the end of the month:
The current version of “Amazon Shopping” APP is 18.14.0.100. I’ve downloaded an APK file and disabled “Automatic Updates” in Google Play Store. Let’s wait and see what will happen…
EDIT: I tried out Amazon Shopping APP today (Aug 4th 2019). And I was still able to configure my DashButtons. So I decided to switch all batteries to brand new long life batteries. Hopefully it will move potential problems into far future.
