public function getContentRating() return ''

public function getContentRating() return '' , actually it has vlaue.
Eg: https://play.google.com/store/apps/details?id=com.endgameinteractive.betrayalio
I hope get '12 岁以上' but return '' instead.

And I find if change the code:
$contentRating = $appInfo[111][1] ?? ''; -> $contentRating = $appInfo[9][0] ?? '';

It will return the value;

My version:
"nelexa/google-play-scraper": "0.4.0.9",
Code place:
/nelexa/google-play-scraper/src/Scraper/AppInfoScraper.php at line 113
