The extension in question requires
mobiledetect/mobiledetectlib:^2.8 which is not compatible with PHP 8.1. The error we’re seeing in the logs is below.
Deprecated Functionality: preg_match(): Passing null to parameter #2 ($subject) of type string is deprecated in /vendor/mobiledetect/mobiledetectlib/Mobile_Detect.php on line 1019  
We need this addressed in the short term since this problem is affecting our daily activities.
