OBDLINK CX vs ABRP - Volkswagen ID.5

he ABRP app, when connecting directly via Bluetooth to the OBDLink CX, shows different data than the on-board computer in my ID.5. For example... according to the car's computer, it has 67% battery, but ABRP reads that I have 66% or even 65% and estimates I'll arrive at my destination with 64%. A moment later, my car drops to 64% while still far from the destination, yet ABRP still shows that I will arrive with 64%.

I bought the OBDLink because I thought LIVE DATA would work perfectly, but that's not the case. I have the latest version of ABRP and I've updated the OBDLink CX to the latest firmware 5.12.4. The Bluetooth icon at ABRP App is green, so I assume it's reading the data correctly. In the car settings within the ABRP app, I can't adjust anything up or down (like I can with ENODE) because this feature is unavailable and labeled as ODB BLP - or at least, that's what it looks like to me.
