Take the following useragent:
Mozilla/5.0 (Linux; Android 11; SM-G991B Build/RP1A.200720.012; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/91.0.4472.120 Mobile Safari/537.36 EdgW/1.0
What does EdgW mean?
(source: https://blogs.windows.com/msedgedev/2017/10/05/microsoft-edge-ios-android-developer/)
but what does EdgW mean? Especially given that the useragent states that the user is using an Android device
we believe that this is an Edge WebView (this is just a guess so far) https://github.com/matomo-org/device-detector/issues/6636
