Proposal

Please re-state the problem that we are trying to solve in this issue.

LHN not displayed after page refresh from settings page. Also, menu options inside the about page are not clickable.

What is the root cause of that problem?

Coin animation loading freezes the page.

https://github.com/Expensify/App/blob/8ec71d6d0ff38f58f2c07396a0963359382ba82a/src/pages/settings/AboutPage/AboutPage.tsx#L148

What changes do you think we should make in order to solve the problem?

We can do an async load of the animation in this way:

Add the below in Lottie/index.tsx:

const [animationFile, setAnimationFile] = useState<string | AnimationObject | {uri: string}>();

useEffect(() => {
    setAnimationFile(source.file);
}, [setAnimationFile, source.file]);

Now, update to return the below:

animationFile ? <LottieView
    // eslint-disable-next-line react/jsx-props-no-spreading
    {...props}
    source={animationFile}
    ref={ref}
    style={[aspectRatioStyle, props.style]}
    webStyle={{...aspectRatioStyle, ...webStyle}}
    onAnimationFailure={() => setIsError(true)}
/> : null

This will fix it for all usages of Lottie animations.

Thank @ShridharGoel proposal, but this issue also happens on other settings screens that use Lottie. This issue only started occurring in a few recent releases, so could you please find the offending PR?

[ShridharGoel]

@suneox It has started happening because we have switched to concurrent mode. We can fix this at all places using a common base logic for Lottie animations.

[suneox]

@suneox It has started happening because we have switched to concurrent mode.

@ShridharGoel Thank you. I also tried reverting the code before the merge commit #42592, and the issue doesn’t happen. It only occurs after commit d047467a enabled React concurrent mode.

We can fix this at all places using a common base logic for Lottie animations.

We don’t need to fix this at all places using Lottie; we just need to fix it in Lottie/index.tsx.

@iwiznia We can fix this issue based on this proposal and implement the fix in Lottie/index.tsx. I have tested it, and it works as expected.

[ShridharGoel]

We don’t need to fix this at all places using Lottie; we just need to fix it in Lottie/index.tsx.

Yes, that's what I meant by the common base logic. Will update to include code example.

[suneox]

Waiting for @ShridharGoel to create the PR.

[ShridharGoel]

Will open PR by tomorrow.
