I always thought that call recording was something trivial until a few days back. Now, my call recorder does not support Google pixel 2xl after the update and there is nothing I can do about it (to my knowledge). I need someone that experienced a similar issue and got the solution for it!
Did you recently update your phone? What version of Android you are using? Maybe due to any recent update to your phone may have malfunction your call recording apps.
Try any of these call recorders
