Continued movement does not, by itself, show that Android's Remove animations setting failed. Identify the particular movement you are observing, then separate interface transitions from content with its own playback.
Change the documented preference
Look under Settings, Accessibility, Colour and motion, Remove animations. The preference reduces supported transitions; app behaviour varies. Device wording can differ. See Google's Android motion settings.
Use an ordinary reading page for your comparison, away from live rounds or consequential controls. Note the setting, then make a short observation of the same screen transition and the same embedded item. Testing two unrelated screens before and after would make the comparison harder to interpret.
Record two separate observations
In a hypothetical example, a phone menu opens with less movement after the preference changes, but a clip embedded in the article keeps playing. Write two lines: “Menu transition reduced” and “Embedded clip continued.” Neither observation cancels the other. Together they describe what changed more accurately than “animations are still on”.
If the embedded item visibly offers its own pause control, that is a different control to consider. Do not invent a hidden control when none is present. A preference for less transition motion is not a promise that a video or remotely managed countdown has stopped, and it cannot extend an external deadline.
Describe the remaining problem
A useful support note identifies the setting, the view and the exact moving item. For example: “Remove animations enabled; help article open; menu transition reduced; embedded clip still moving.” That tells another person what you observed without claiming to know the app's internal implementation.
Do not replace that note with “the game is paused” or “the timer is frozen” unless those separate states have actually been established. If motion remains uncomfortable, leave the page rather than continuing the test. Our screen-change guide offers general reading context; no specific game's support for reduced motion is established here.
