    Just got my Oneplus 9 Pro, honestly enjoying it from my old Pixel 3. The problem comes down to not being able to charge the phone in the car and use the headphone jack into the AUX port on my stereo. I have now tried 3 different adapters, 2 of them listed compatibility with the older Oneplus7 and 8 lines, but they don't work now.

    Was it something in a recent update that broke everything or is it the new phones?
    Are there fixes?

    The charging and failing adapter are 2 separate issues right? (not an adapter that claims to support both AUX and charging at the same time).
    You may want to report the issues with the adapter via the feedback tool.
    Regarding the charging... Not charging at all or just VERY slow? What kind of port/charger?
