I noticed that when I enable Battery Saver on Android 8.1, the indeterminate ProgressBars in the app are not properly shown. This is a known problem in Android API level <28, see e.g. this StackOverflow question. Battery Saver disables animations, also on progress bars on these versions.

Looking at the code, indeterminate progress bars are created here:
To fix this issue, one can check ValueAnimator.areAnimatorsEnabled() and provide a different UI element, such as a text label, when animations are disabled.
I also recorded a video, showing the issue in practice:
