———————————————————————————
I have ABRP connected to my Hyundai ioniq with a OBD2 adapter. Recently the navigation either completely locks up or lags behind several hundred meters. SOC doesn’t update anymore either when this happens. Also the OBD2 adapter‘s lights indicate that there might be a connection problem, although ABRP says it is connected at the same time. I changed in the preferences that the position of the device overrides the position of the car, but that didn’t make any difference. Unfortunately this has made ABRP completely useless for me. I hope you have an idea how to fix this problem.
