Proposal

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

I was not able to find any offending PR within the deploy checklist, so I'm assuming this was not caused by the latest deploy.

What is the root cause of that problem?

We're not leveraging the iOS specific keyboardAppearance TextInput prop and because of this, the 'default' applies which will default to the appearance that the user has set globally on their device, which typically is a light keyboard but will be dark if the user has chosen to use the system-wide dark mode in their iOS settings.

This can cause the unwanted transition from dark to light if not specifically set.

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

Since the Expected result states:

It should only show a grey background.

this means we always want to show the light keyboard background.

For this we should explicitly set keyboardAppearance to light here.

I think #29991 is the offending PR.
So retest after #37305 is deployed to staging

Can confirm it's working fine now after the revert. Closing this issue, but feel free to reopen if there's still something that needs to be done.
