Based on the updates made to iOS14 for implementing the App Tracking Transparency framework ( https://developer.apple.com/documentation/apptrackingtransparency) , the usage of isAdvertisingTrackingEnabled is causing issues as it always returns "DNT" instead of the IDFA.
Our SDK checks "Advertising Tracking Enabled" with the above mentioned deprecated method: "isAdvertisingTrackingEnabled" which always returns false in iOS14
See reference here: https://developer.apple.com/documentation/adsupport/asidentifiermanager/1614148-isadvertisingtrackingenabled
This needs to be reverted immediately, please take appropriate action.
