i love Read Aloud in Google Play Books, but recently the Speech Rate slider stopped working. had to factory reset my phone then check update details to diagnose, this is what's breaking functionality. uninstall, resolved. so that was harder and more tedious/annoying than it had to be. PS, tried uninstall/reinstall, that breaks the Speech Rate and Pitch sliders again, so if anyone's reading, try uninstall, uncheck automatic updates, just leave this off.
