Cordova hybrid app latest IOS OS 14.6 and 14.7 wkwebview certain user local storage was cleared

Hi Team,

this is one of my Cordova hybird iOS apps in production. Certain users' local storage was suddenly cleared off with the latest IOS versions, such as 14.7 and 14.6. Even though the devices had plenty of storage. Recently, we implemented wkwebview instead of UIWebview. We could not find the cause. Could you please help me locate the cause? Thank you.

We are using below configuration: 9.0.0 cordova-lib-9.0.1 ios6.0.0 cordova-plugin-wkwebview-file-xhr 3.0.0 "Cordova WKWebView File XHR Plugin"
