Even debug

I’m using the 0.3.4 library and log is as follows:

I tried to install the new version 0.3.7 and the log is much less readable.

Why this change that reading gets worse?

Sorry, we don’t provide such kind of support. If you want to change the format - the library is open-source and you can change it.
This is not considered a bug or a problem.

Thank you for your availability…

No problem, please ask if you have any other questions!

what library / file I have to go and change the formatting?

Probably here: https://github.com/blynkkk/blynk-library/blob/master/Blynk/BlynkDebug.h#L130
