@justice4all3000 does your cheap ebay OBD scanner connect to your phone app and also to the car?
If it does, are their any DTC (both hard and pending fault codes). The existence or not of a fault codes is the only relevant point. It tells us one of two things: either there are fault codes (which would be useful) or that there may be fault codes within some module that your OBD scanner can’t detect (which also would be interesting to know).

@chrisp posted, it’s clearly stated that calibration process will not start automatically using SPS and must be initiated with GDS2. Being that the commodore is a GM product, I doubt they reinvented the wheel here so it would almost certainly be the same.
VF is GDS2 base as I understand. Buying a clone GM MDI with GDS2 software and a GM subscription should allow you to sort this out yourself..... assuming the s/w is well written and guides you through the required actions.
How much it will cost for a decent clone, I’m not sure, but I’ve never liked subscription based systems... I’ll likely go down this route when my toy is past warranty.
