SoC isn't accurate while Bluetooth to car

App reports car is at 67% SoC and charging at 11kw. Car is actually at 38% and was moving at 43 mph and ABRP was navigating me. Noticed as 2023 Chevy Bolt's remaining bars didn't match what ABRP stated my arrival SoC nor starting SoC was.
I do have a screen recording I grabbed while this was happening.

Hi Craig
I'm driving the sister car, an Opel Ampera-e, which is technically identical to the Chevrolet Bolt EV, using also ABRP live data.
Like many vehicles, the Bolt EV also has two different SOCs:
the net usable SOC which is quasi displayed on the cockpit with the bars, and the real gross SOC.
ABRP uses the gross SOC. Therefore, a deviation between the ABRP SOC value and the cockpit bar value can be explained.
However, 29% deviation is clearly too much and indicates a problem.

I wouldn't have even noticed if it was a few percent off, since the bars show a 5% jump between. And I use the bars as more of a glance for a rough approximation. I used ABRP the night in question because I knew I was getting a bit low and wanted the actual number and the MyChevrolet Android app doesn't show me my SoC - only way to get the actual number is via ABRP that I've found.
I got the 38% actual value from the MyChevrolet app (via phone) after I realized there was a difference between the bars and the displayed SoC in the ABRP app.

Did the values of Cockpit and ABRP match until recently, or have they not been identical since the beginning?

Recently, this night was the 1st time I've noticed a difference. I've used it before on multiple trips without issue, using it to judge when I needed to stop at a Level 3 or if I could bypass and get home without a charge somewhere.
