Review Sentences can get stuck on loading

[Sobsz]

My Sentence Collector session entered a "stuck" state. In this state, the "Review" section perpetually displays a spinner with the text "Loading sentences...", even when no language is selected. All other sections work fine. Debugging shows that no request is ever made to review?locale=[language] is ever made.

The "stuck" state can be removed by editing the local storage key persist:sentences to remove sentencesLoading:"true", but this cannot be done without access to a trusted computer. None of the following mobile-only methods solved the issue:

• logging out and back in (whether via Firefox account or passwordless login)
• force-stopping Firefox
• disabling all addons and Enhanced Tracking Protection
• switching from mobile data to Wi-Fi

Switching browsers or using Incognito mode do allow the user to sidestep the issue. Removing browsing data would solve, too, but I could not find a way to do so for one site only on Firefox Android.

Running Firefox 97.2.0 on Android 11. My Internet connection was being spotty today, which I believe might have caused the problem.

Thanks for this thorough bug report and all the debugging done. This makes it fairly straightforward to fix.

We are persisting the sentences state with a few exceptions here: https://github.com/common-voice/sentence-collector/blob/main/web/src/reducers/index.ts#L21

To make sure we are not persisting the loading states, we should add both isUploadingSentences and sentencesLoading to the exceptions linked to above. Then saving the state while a request is reloading wouldn't result in this scenario.

Great catch!
