If you’re a Voiceover user & your device is running ios 17.1.1 or newer, you may have run into an issue, where Voiceover loses its label for this button.
When I had this issue, voiceover would just say, “button” when encountering the search tab of the following applications. Mona, Which is a third-party mastodon app, the App Store and Apple podcasts.
To work around this, I labeled the button by doing the following. Note: you only need to do this once and it will work everywhere, this bug has appeared.
Triple tap one of the applications listed above.
2. Activate the search button and perform a two finger triple tap and hold. This is the label element command.
3. In the field that comes up, type the word search and press return.
