Webflow Site + Android Webview & Disparity between FB Ads and Google Analytics


We have created some ads on Facebook and Instagram and I have noticed on Google Analytics that visitors using Android Webview on their mobile do not spend more than 4 seconds on the site. These 4 secs are to be compared to people using Chrome or Safari (on their mobile) who spend an average of 1 min and 30 secs.

Another issue is that according to Facebook, there have been 900+ link clicks for our ads, but according to Google Analytics, we only have 150-160 people landing on our website. Based on the data captured, most people are using Android Webwiew.

Most of our users are mobile visitors using Android Webview.

Do you have any idea on how to solve this problem with the browser Android Webwiew and the disparity between GA and FB ads? Is the same issue causing these two problems or there could be something else? This is our site: https://www.bottomlessbrushes.com/
