Hi there,
Fair enough… I understand and agree somewhat. I too have a similar background on a global scale (" Link in the description" LOL always wanted to say that 
) but more towards the hardware.
The line is becoming so blurry 
these days and THANK YOU for touching @Massar_sara on the info too.
You may also be correct about the issue as well for her board.
They are looking at it closer now, thanx to you. 
I dunno what happened and can’t speak for them AFAIK the previous revs worked well.
They (seeed) do need a better understood trouble ticket or escalator system for issues like yours. the “read the WiKi” isn’t going to cut it.
Again glad you got it going forsure
