I installed the the ELM327 for my 2017 Volt days ago. When can I expect to see the battery report?
Where are the instructions for using MyGreenVolt?

Such documentation as I've found is here: More

There are tabs, or a pulldown menu of tabs, depending on your screen orientation. Tapping "batt cell" (I think that's it) will switch to the cell voltage display. If it says "PURCHASE" in the corner, you're looking at a demo screen and need to buy the upgrade for a dollar. Cell voltages change A LOT so only expect consistency/reliability when the car is on, but parked for a minute or two, and engine has turned itself off. Fresh off a charger will show you how well the balancing has worked (cells should be very close together in the min/max read out at the bottom, but will hide weak cells from you. Doing a reading when the battery has been discharged and the car has switched to engine at least once will show weak cells if there are any, and you'll see a bigger deviation between the min and max in mV.
I did buy the app. And it's been a few days and the Batt Cell tab is still blank.
"cells should be very close together in the min/max read out at the bottom" - Please define "very close""?
did you buy the app or make the in-app purchase to see the batt cell voltages?
it should work immediately, does any other data display on the other tabs?

Everything, every tab, every page is all zero. Except the Bluetooth tab: "Already connected to OBDII"
You didn't specify your phone system ... Google Android or Apple iOS but I'm guessing Apple now since it looks like you pay upfront for that. Android is a free app and $1 for cell details.
Apple iOS: ‎MyGreenVoltConnect
Google Android: MyGreenVolt - Apps on Google Play

This site had an email contact. See "Support" section: MyGreenVolt
I appreciate your assistance.
I clicked on the "Purchase" button on the app on my Android phone. Was I supposed to do it differently?
That's the right thing to do, but that was the first time you've said that's what you did in a way that was clear about that you did this particular thing. So, app installed, cell readout purchased. Car on? Reader dongle plugged into OBD port, reader dongle paired with app? App showing data on the main dashboard?
All yes, but all of the data on the app dashboard is zero.
Good points above by hellsop and jbakerjonathan

I would look for free returns (in case it doesn't work) ... $20-$30 range ... 5000+ reviews w/4+ starts ...

3 examples

I'm using a more expensive one that handles large amounts of data for my Tesla (and works my our Volts)
Thanks- This is the one I bought on a recommendation from the Volt forum on Facebook.

So, any of the three you listed above should work with then GmVolt app?
As I said, it was recommended by another user on the Volt Facebook forum who uses it in his Volt.
