I don’t really understand what you are saying here.
You seem to be saying that no values are being updated in the app, either integers or floats. Is this correct?
I’d suggest that you post your updated sketch.
When you post serial monitor output it needs to be text, not a screenshot, and it needs to be formatted with triple backticks.
I’d suggest you post your serial output from boot-up, so we can see the Blynk logo and connection data, as well as some values.
You need to be clear about exactly what is being displayed in the dashboard, and whether this is the mobile or web dashboard (or both).
Your issue does sound similar to this one…
but that was fixed (at least for the nano) in the latest release.
