fluctuating SOC and destination SOC

[DrewU]

I use ABRP with my ID4 and an Obdlink CX.  I used Android Auto and lately in a trip I've planned I'm getting fluctuating SOC numbers and destination SOC numbers.  It seems like it reads the battery correctly and displays that along with the destination SOC and then a few seconds later, the current SOC drops by several percentages along with the destination SOC.  Then it corrects itself and show the correct numbers only to have this happen repeatedly throughout the trip, constantly switching from one set of numbers that seems accurate to some other wildly inaccurate numbers.  It only started doing this recently. Not sure what's happening. Don't know if it's an ABRP issue, or an issue with my obdlink device. Thanks for any help.
