with each new update, I keep losing more and more data sets that transmit back from my sensors. At first I had temperature and battery voltage and for some reason the battery voltage just quit. No code changes nothing just decides to stop. All the hardware that I made is the same. nothing changed other than updates to the app and how my data is handled by Blynk.

When I had the previous version of Blynk I spent a few dollars on energy which is now worthless. I think at least they could make the amounts spent on energy available in subscription discounts. Even so, I won't pay as it's a non-commercial learning project. The widgets available on the free plan are VERY limited. It doesn't make sense to me. I'm going to look for another more complete platform that serves me free of charge for small projects.
